Subject: [PATCH] lottie: integrate JerryScript engine for expressions

introduced the JerryScript engine to interpret Lottie
expressions, enhancing the capability to support runtime
programmable animation logic within Lottie expressions
spec. This feature, based on js scripting, represents
the most complicated addition to the Lottie spec so far.

ThorVG probably could includes an option to toggle
this feature at build time, allowing for customizable user
configurations according to specific requirements.

removed unused features for the optimal size:
- DEBUGGER
- MEM_STATS
- SNAPSHOT
- BUILTIN_JSON
- BUILTIN_PROXY
- BUILTIN_REFLECT
- BUILTIN_ATOMICS
- PROMISE_CALLBACK
- MODULE_SYSTEM
- SYSTEM_PORT

This is an experimental version.
Please manually enable the 'lottie-expressions' in meson.build
when you wish to use it.

See: https://jerryscript.net/

+ * than 16 bits: 0x0 - 0x10FFFFF). One code point could be represented with one ore two 16-bit code units.
+ *
+ * According to the standard all strings and source text are assumed to be a sequence of code units.
+ * Length of a string equals to number of code units in the string, which is not the same as number of Unicode
+ * characters in a string.
+ *
+ * Internally JerryScript engine uses UTF-8 representation of strings to reduce memory overhead. Unicode character
+ * occupies from one to four bytes in UTF-8 representation.
+ *
+ * Unicode scalar value   | Bytes in UTF-8             | Bytes in UTF-16
+ *                        | (internal representation)  |
+ * ----------------------------------------------------------------------
+ *  0x0     - 0x7F        |  1 byte                    |  2 bytes
+ *  0x80    - 0x7FF       |  2 bytes                   |  2 bytes
+ *  0x800   - 0xFFFF      |  3 bytes                   |  2 bytes
+ *  0x10000 - 0x10FFFF    |  4 bytes                   |  4 bytes
+ *
+ * Scalar values from 0xD800 to 0xDFFF are permanently reserved by Unicode standard to encode high and low
+ * surrogates in UTF-16 (Code points 0x10000 - 0x10FFFF are encoded via pair of surrogates in UTF-16).
+ * Despite that the official Unicode standard says that no UTF forms can encode these code points, we allow
+ * them to be encoded inside strings. The reason for that is compatibility with ECMA standard.
+ *
+ * For example, assume a string which consists one Unicode character: 0x1D700 (Mathematical Italic Small Epsilon).
+ * It has the following representation in UTF-16: 0xD835 0xDF00.
+ *
+ * ECMA standard allows extracting a substring from this string:
+ * > var str = String.fromCharCode (0xD835, 0xDF00); // Create a string containing one character: 0x1D700
+ * > str.length; // 2
+ * > var str1 = str.substring (0, 1);
+ * > str1.length; // 1
+ * > str1.charCodeAt (0); // 55349 (this equals to 0xD835)
+ *
+ * Internally original string would be represented in UTF-8 as the following byte sequence: 0xF0 0x9D 0x9C 0x80.
+ * After substring extraction high surrogate 0xD835 should be encoded via UTF-8: 0xED 0xA0 0xB5.
+ *
+ * Pair of low and high surrogates encoded separately should never occur in internal string representation,
+ * it should be encoded as any code point and occupy 4 bytes. So, when constructing a string from two surrogates,
+ * it should be processed gracefully;
+ * > var str1 = String.fromCharCode (0xD835); // 0xED 0xA0 0xB5 - internal representation
+ * > var str2 = String.fromCharCode (0xDF00); // 0xED 0xBC 0x80 - internal representation
+ * > var str = str1 + str2; // 0xF0 0x9D 0x9C 0x80 - internal representation,
+ *                          // !!! not 0xED 0xA0 0xB5 0xED 0xBC 0x80

+ *    The format is big endian.
+ *
+ * Small:
+ *    One byte can encode signed values between 127 and -126.
+ *    Two byte can encode signed values between 319 and -318.
+ *    Large values are encoded with vlq with a prefix byte.
+ *
+ * The line-info data structure is a sequence of chunks:
+ *
+ *  +------+--------------+------------+----------------+
+ *  | Line | StreamLength | StreamData | [ByteCodeSize] |
+ *  +------+--------------+------------+----------------+
+ *
+ *  Line [Vlq encoding]:
+ *      Specifies the start line of this chunk, relative to its previous value.
+ *      The starting column is always ECMA_LINE_INFO_COLUMN_DEFAULT
+ *
+ *  StreamLength [uint8_t]:
+ *      Length of the StreamData in bytes minus ECMA_LINE_INFO_STREAM_SIZE_MIN.
+ *      The 0 value represents the last chunk, which size is not specified
+ *      (Can be less than ECMA_LINE_INFO_STREAM_SIZE_MIN).
+ *
+ *  StreamData [sequence of bytes]:
+ *      Sequence of the following items:
+ *
+ *      +-----------+--------+--------+
+ *      | EndOffset | [Line] | Column |
+ *      +-----------+--------+--------+
+ *
+ *      EndOffset [Small encoding]:
+ *          Specifies the EndOffset in the byte code, relative to the previous EndOffset.
+ *          The range of byte codes corresponding to the line/column position of this item
+ *          is between the EndOffset of the previous item (inclusive) and the EndOffset
+ *          of this item (exclusive). The last end offset of a stream is always 0, which
+ *          represents an unterminated range.
+ *
+ *      Line [Small encoding] [Optional]:
+ *          If bit 1 of end offset is set, this specifies the line position of this item,
+ *          relative to the previous line position, and the column position is set to
+ *          ECMA_LINE_INFO_COLUMN_DEFAULT.
+ *
+ *      Column [Small encoding]:
+ *          Specifies the current column position relative to the previous column position.
+ *
+ *  ByteCodeSize [Vlq encoding] [Optional]:
+ *      If StreamLength is not 0, this specifies the byte code size of the whole range.
+ *      This value can be used to skip the byte codes which line info is stored
+ *      in this chunk. This information is not available for the last chunk.

+ * During byte code post processing certain bytes are not
+ * copied into the final byte code buffer. For example, if
+ * one byte is enough for encoding a literal index, the
+ * second byte is not copied. However, when a byte is skipped,
+ * the offsets of those branches which crosses (jumps over)
+ * that byte code should also be decreased by one. Instead
+ * of finding these jumps every time when a byte is skipped,
+ * all branch offset updates are computed in one step.
+ *
+ * Branch offset mapping example:
+ *
+ * Let's assume that each parser_mem_page of the byte_code
+ * buffer is 8 bytes long and only 4 bytes are kept for a
+ * given page:
+ *
+ * +---+---+---+---+---+---+---+---+
+ * | X | 1 | 2 | 3 | X | 4 | X | X |
+ * +---+---+---+---+---+---+---+---+
+ *
+ * X marks those bytes which are removed. The resulting
+ * offset mapping is the following:
+ *
+ * +---+---+---+---+---+---+---+---+
+ * | 0 | 1 | 2 | 3 | 3 | 4 | 4 | 4 |
+ * +---+---+---+---+---+---+---+---+
+ *
+ * Each X is simply replaced by the index of the previous
+ * index starting from zero. This shows the number of
+ * copied bytes before a given byte including the byte
+ * itself. The last byte always shows the number of bytes
+ * copied from this page.
+ *
+ * This mapping allows recomputing all branch targets,
+ * since mapping[to] - mapping[from] is the new argument
+ * for forward branches. As for backward branches, the
+ * equation is reversed to mapping[from] - mapping[to].
+ *
+ * The mapping is relative to one page, so distance
+ * computation affecting multiple pages requires a loop.
+ * We should also note that only argument bytes can
+ * be skipped, so removed bytes cannot be targeted by
+ * branches. Valid branches always target instruction
+ * starts only.
