0fc2e6adcb portability: fix file size check on Windows 
Resolved an issue where parsing failed due to mismatch
between file size obtained via `ftell` and the actual
bytes read by `fread`. This occurred because newline
translation (`\r\n` to `\n`) in text mode altered the byte
count, leading to incorrect assumptions about the data size.

00324f5e19 lottie: revise the masking logic 
- Allow the masking data even though they were mask None mode.
  Those will be used by the layer stroke effect.
- Fixed masking Offset to apply to all masking chains.
- Optimized fast track masking with resolving the opaicty condition.
- Clean up the overall code.

52cf31a79d renderer: make the file io configurable 
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.

a851d1706e lottie: fix transformations in text range selector 
Since the translate API was used while text updating,
the subsequent range selector transformations gets overwritten
when updating the shape (scale and rotate, adding another
translation will persist). This caused unexpected results.
Fixed by using the transform API when additional transformations
are needed - also fixes applying more than one range selector.

269e6c4d10 lottie: offset does not depend on shape direction 
According to tests in AE, the offset direction should
not depend on the direction of the shape. A positive
offset value expands the shape, while a negative value
contracts it. Fixed.

4c0765b761 lottie: fix offset 
For long Bezier curves compared to the offset value,
the offsetting algorithm caused deformation. The problem
became evident after adding mask extension, as the simple
shapes defined there are based on Bezier curves rather
than as shapes like a circle/rect/etc, which is the case
for the offset. Now fixed.
