b77f3ca024 common: introduced designated memory allocators
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

78cfc33f4c lottie: support frame tweening feature
frame tweening allows user to interpolate two frames
over a speicified duration. This Tweening functionality
can be particularly powerful when combined with state-based
(a.k.a. Marker) animation playback in Lottie.

For example, apps support state machine based animations,
where the transition sequences between states are not linear
and can occur in highly irregular directions.

Experimental APIs:
- Result LottieAnimation::tween(float from, float to, float progress)
- Tvg_Result tvg_lottie_animation_tween(Tvg_Animation* animation, float from, float to, float progress)

dfd7693158 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.

87d85047aa lottie: add offsetPath support
Due to the lack of an analytical solution for Bezier
curves offsetting, a simple and computationally cheap
approximation has been implemented. The algorithm shifts
the segments connecting control points and determines
new points based on their intersections.

3a8ef78a36 lottie: fix interpolation issue
Handled the case of different numbers
of points in consecutive frames. This
case can occur due to erroneous data

81ff238fef lottie/expressions: enhance stability
When the system fails to interpret the expression code,
it forcibly disables the feature per property.

This improvement enhances stability and performance
by avoiding reckless attempts to interpret JavaScript code.

When we confirm the full stability with expressions,
we can revert this code.

Therefore, when tvg::Initializer::init() is configured
with more than one thread, expressions will be automatically disabled.
