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

lottie: parsing embedded fonts data (#3220)
Only parsing and font loading is added with
a very basic text update while building the scene.

391777091c lottie: ++ dashed stroke support
Until now lottie loader supported only a single
dash-gap pair, and only the case where only the dash
was provided was handled correctly. When both values
were provided, the gap was incorrectly increased by
the dash value. If more values were supplied, only
the last pair was considered.

cc4c18d6c6 renderer: revise the Shape rect/circle features
The path direction of shapes is now functional for path trimming.
Replace the main logic with Lottie's by default
to align the spec, migrate the original logic to svg loader side.

This revision helps to reduce the binary size by 2–3 KB for lottie loader.

API Modifications:

- Result Shape::appendRect(float x, float y, float w, float h, float rx = 0, float ry = 0)
 -> Result Shape::appendRect(float x, float y, float w, float h, float rx = 0, float ry = 0, bool cw = true)
- Result Shape::appendCircle(float cx, float cy, float rx, float ry)
 -> Result Shape::appendCircle(float cx, float cy, float rx, float ry, bool cw = true)
- TVG_API Tvg_Result tvg_shape_append_circle(Tvg_Paint* paint, float cx, float cy, float rx, float ry)
 -> TVG_API Tvg_Result tvg_shape_append_circle(Tvg_Paint* paint, float cx, float cy, float rx, float ry, bool cw)
- Tvg_Result tvg_shape_append_rect(Tvg_Paint* paint, float x, float y, float w, float h, float rx, float ry)
 -> Tvg_Result tvg_shape_append_rect(Tvg_Paint* paint, float x, float y, float w, float h, float rx, float ry, bool cw)

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)

096b834771 lottie: fix text stroke's 'of' property
The text stroke's 'of' property determines whether
the stroke appears above (true) or below (false)

the stroke would render.

1806b32971 common: optimization pImpl data structures

d9be58d4b7 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.
