reduz ae1c016547 Implement Animation Blend Shape Tracks
* New track type BLEND_SHAPE
* Blend shapes are imported via this new track type
* Processing is more optimized (no longer relies on variants)
* Modified the Blend Shape API in MeshInstance3D to use indices rather than StringNames (more optimizes)
* Promo: Fixed a small bug in gizmo updating in Node3D that affected performance

Dedicated BlendShape tracks are required for both optimization and eventually implementing them in animation compression.

Node that instances meshes into a scenario.
</brief_description>
<description>
MeshInstance3D is a node that takes a [Mesh] resource and adds it to the current scenario by creating an instance of it. This is the class most often used render 3D geometry and can be used to instance a single [Mesh] in many places. This allows reuse of geometry which can save on resources. When a [Mesh] has to be instantiated more than thousands of times at close proximity, consider using a [MultiMesh] in a [MultiMeshInstance3D] instead.

<method name="create_convex_collision">
<return type="void" />
<argument index="0" name="clean" type="bool" default="true" />

<description>
This helper creates a [StaticBody3D] child node with a [ConvexPolygonShape3D] collision shape calculated from the mesh geometry. It's mainly used for testing.
If [code]clean[/code] is [code]true[/code] (default), duplicate and interior vertices are removed automatically. You can set it to [code]false[/code] to make the process faster if not needed.
If [code]simplify[/code] is [code]true[/code], the geometry can be further simplified to reduce the amount of vertices. Disabled by default.

<method name="create_multiple_convex_collisions">
<return type="void" />
<description>
This helper creates a [StaticBody3D] child node with multiple [ConvexPolygonShape3D] collision shapes calculated from the mesh geometry via convex decomposition. It's mainly used for testing.

<method name="get_active_material" qualifiers="const">
<return type="Material" />
<argument index="0" name="surface" type="int" />
<description>
Returns the [Material] that will be used by the [Mesh] when drawing. This can return the [member GeometryInstance3D.material_override], the surface override [Material] defined in this [MeshInstance3D], or the surface [Material] defined in the [Mesh]. For example, if [member GeometryInstance3D.material_override] is used, all surfaces will return the override material.
