Add support for removing attributes from meshes. (#5254)

Browse Source 
# Objective

Support removing attributes from meshes. For an example use case, meshes created using the bevy::predule::shape types or loaded from external files may have attributes that are not needed for the materials they will be rendered with.

This was extracted from PR #5222.

## Solution

Implement Mesh::remove_attribute().
