Support the bindings to be more integrable with a system's coherent memory management.
Pleaes note that thorvg now only allow the desinated memory allocators here:
malloc -> tvg::malloc
calloc -> tvg::calloc
realloc -> tvg::realloc
free -> tvg::free

certain systems, may not support file I/O operations.
ThorVG should provide users with an option to configure
builds according to their requirements.
This ensures that file I/O calls are avoided,
preventing potential crashes.
Please use the meson '-Dfile=true/false' option for this.
Please note that "THORVG_FILE_IO_SUPPORT" might be expected
for your thorvg manual build.

Remove the requirement for unique_ptr in the function prototypes.
This change will simplify the API usage, making it more streamlined
and user-friendly. However, memory management will now be the
responsibility of the user.

Text can be added in parts due to the presence
of the <tspan> tag. This requires that each
subsequent piece of text is appended rather than
overwriting the previous one.
Since the text node wasn't pushed onto the loader's stack,
closing the text node incorrectly caused an element to be
popped from the stack (if one was present).
This could result in elements that were supposed to have
that element as a parent being rendered incorrectly or not
being rendered at all.
Now, the text node is correctly pushed onto the stack.

The range of saturation and brightness values is 0 ~ 100% and range of hue is 0 ~ 360.
If a value greater than 100% is loaded, it will be modified to be 100%.

loader->stack.pop() at line 3271 is called to remove
the defs node added to the stack due to nested graphics elements.
However, it is called in an inappropriate situation and the loader's node tree is damaged.
Fixes an error where the close tag is recognized as a `line` of the graphics tag when it is `linearGradient`.
ex)
```
<defs id="def">
<linearGradient x1="1" y1="2" x2="3" y2="4" id="l"/>
</linearGradient>
<rect x="10" y="10" width="10" height="10" fill="blue" id="r2"/>
</defs>
```

The text node is handled, but default values
of the font-family and font-size as used in
the user's system are not.
For now font has to be loaded by the user.

Rather than aiming for extremely high accuracy,
a compromise can achieve with better performance.
This modification helps prevent unnecessary image rotation.

The display property, like any other node's style property,
should be part of a node style. This ensures its correct
copying and inheritance.
For the 'symbol' node, which is not rendered unless it is
used within a 'use' node, the display property can also be
applied. Because of that it cannot be utilized during scene
construction to determine whether the symbol is being defined
or used within a 'use' context.
The display property was not copied along with other
node properties. This caused incorrect rendering
of an object with display=none if accessed through
a use tag.
This reverts commit 75e587a9a9.
If incorrect data for the points in a polygon is provided,
the element should still be rendered, but only up to the point
where the error occurs—using an even number of the points that
have been successfully loaded.
Because memcpy() is not guaranteed to copy null at the end of the data array,
it increase the size by 1 and add null
This prevents invalid access of string functions in parser.
When finding the 'nodeFrom' referenced by `<use>`,
if it is the parent, it is not referenced.
https://www.w3.org/TR/SVG2/struct.html#UseElement
Specification:
If the referenced element is a (shadow-including) ancestor
of the ‘use’ element, then this is an invalid circular reference
and the ‘use’ element is in error.

Improve parenthesis checking and space checking.
- There must be only one pair of parentheses.
- There cannot be spaces(and ') between id strings.
