feat(extra-natives-five): add msgpack support for scripted animation natives

[Rogui20]

Goal of this PR

This PR makes TASK_SCRIPTED_ANIMATION and PLAY_ENTITY_SCRIPTED_ANIM usable from script runtimes by allowing their animation data parameters to be passed as msgpack objects.

These natives expect internal animation slot data structs. This PR converts structured script data into the layout expected by the game native before forwarding the call.
...

How is this PR achieving the goal

This PR registers wrappers for:

• TASK_SCRIPTED_ANIMATION
• PLAY_ENTITY_SCRIPTED_ANIM

The wrappers:

• read fx::scrObject msgpack arguments from the script runtime;
• deserialize them into std::map<std::string, msgpack::object>;
• populate a ScriptInitSlotData layout expected by the native;
• keep string storage alive while assigning the internal string pointer fields;
• replace the script arguments with pointers to the generated structs;
• forward the call to the original native handler.

Empty or malformed msgpack data falls back to a default empty animation slot, allowing unused slots to be passed as an empty string or an empty msgpack object.

The native behavior itself is unchanged. This PR only adds argument translation.

Lua usage example

local data = msgpack.pack({
state = 1,
dict0 = "clip@chopper_generic",
clip0 = "hover",
phase0 = 0.0,
rate0 = 1.0,
weight0 = 1.0,
filter = 0,
blendInDuration = 0.1,
blendOutDuration = 0.1,
timeToPlay = -1,
flags = 1,
ikFlags = 0
})

Scripted animation data fields

Each animation slot object can define up to three clips:

state
dict0, clip0, phase0, rate0, weight0
dict1, clip1, phase1, rate1, weight1
dict2, clip2, phase2, rate2, weight2
filter
blendInDuration
blendOutDuration
timeToPlay
flags
ikFlags

Known state values:

0: disabled / empty slot
1: single clip
2: blended slot using the configured clip entries
