feat(extra-natives-five): Add msgpack wrapper support for TASK_SCRIPTED_ANIMATION

[Rogui20]

Goal of this PR

This PR allows TASK_SCRIPTED_ANIMATION and PLAY_ENTITY_SCRIPTED_ANIM natives to accept msgpack objects from scripting runtimes (Lua/JS/C#) and convert them into the ScriptInitSlotData structure expected by the game.

This enables scripts to configure scripted animation slots using structured data rather than requiring native-side struct construction.

How is this PR achieving the goal

This PR registers lightweight wrappers for the following natives:

TASK_SCRIPTED_ANIMATION

PLAY_ENTITY_SCRIPTED_ANIM

The wrappers:

Read the msgpack object (fx::scrObject) passed from the scripting runtime.

Deserialize it into a std::map<std::string, msgpack::object>.

Populate a ScriptInitSlotData struct matching the exact layout expected by the native.

Update internal string pointers after construction to ensure valid lifetime.

Replace the arguments in the ScriptContext with pointers to the generated structs.

Forward the call to the original native handler.

Invalid, empty, or malformed msgpack objects automatically fall back to a default empty slot using FillDefaultScriptInitSlotData, allowing scripts to omit unused animation slots safely.

The native behavior itself remains unchanged; this PR only adds argument translation.

This PR applies to the following area(s)

Natives
ScRT: Lua
ScRT: JS
ScRT: C#
