Creating a trimesh static body from a mesh with blend shapes does not take blend shapes into account

[Astavie]

Godot version:
3.2.2

OS/device including version:
Linux Mint 20

OpenGL ES 3.0 Renderer: GeForce 940MX/PCIe/SSE2

Issue description:
When you have a model imported with blend shapes, and you create a trimesh static body from it, it ignores the blend shape settings you have provided and creates the static body as if all keys were 0.

So this is my model:

But this is the collision shape:

Little project:
Open res://level/lvl1.tscn for the mesh

now that we can bake mesh from blend shapes mix (#76725), there's now a workaround to do this by replacing the collision shape with the baked array mesh. However, should godot support doing this directly instead? Perhaps with an optional parameters on the create_collision functions on mesh_instance_3d?
