feat(extra-natives-five): add Lua support for scripted animation data buffers

[Rogui20]

Goal of this PR

Allow Lua scripts to call TASK_SCRIPTED_ANIMATION and PLAY_ENTITY_SCRIPTED_ANIM using data buffers that contain animation dictionary and clip name strings.

These natives expect structures containing char* fields, which are currently difficult to populate from Lua without exposing raw pointers to scripts or implementing native-specific wrappers.
...

How is this PR achieving the goal

This PR adds support for inline string markers inside binary buffers passed to scripted animation natives.

When a buffer contains a string marker in the form:

__cfx_str:

the marker is resolved into a temporary native string and replaced with a valid char* before the native is executed.

This allows Lua scripts to build the animation initialization structure entirely from script-side data while keeping string pointer creation inside the runtime.

The implementation was designed specifically to support the structures used by:

TASK_SCRIPTED_ANIMATION
PLAY_ENTITY_SCRIPTED_ANIM

without exposing raw memory addresses to scripts.
