Remove animation 3D transform track, replace by loc/rot/scale tracks.

[reduz]

Supersedes #53473

• Animation.TYPE_TRANSFORM3D track is gone.
• Added POSITION_3D, ROTATION_3D, SCALE_3D tracks.
• GLTF2, Collada, FBX importers will only import the track types found.
• Skeleton3D bone poses are now Pos/Rot/Scale, pose matrix removed.
• AnimationPlayer and AnimationTree animate these tracks separately, only when found.
• Removed BakeReset code, is useless with these changes.
• Removed AnimationCache, I have no idea what it was but it seemed unused.

New tracks in the animation editor:

This is the first in a series of commits designed to make the animation system in Godot more useful, which includes:

• Better compatibility with Autodesk products
• Better reusability of animations across models (including retargeting).
• Proper animation compression.
• etc.

Upcoming PRs after this: Track import behavior selection, un-linking of rest/pose matrices in bones (bones becoming pose only), animation compression.

Note GLTF2 animation saving went broken with this PR, needs to be fixed in a subsequent one.

For a future date run the svg processing tools.

Playing the scale animation track causes a crash.

[fire]

I can't recreate the crash, but the motions in the sample for cubic and for stepwise scale don't play.

[fire]

Test cases work. 🌮
