[WIP] [Physics] Restore mesh implementation state from PR #289

[Eideren]

PR Details

As mentioned on PR #289 this PR only addresses creating static mesh colliders from mesh assets, static mesh colliders can already be created from vertex positions + triangle indices.

Related Issue

None.

Motivation and Context

See PR #289.

Types of changes

• Docs change / refactoring / dependency upgrade
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Checklist

• My change requires a change to the documentation.
• I have added tests to cover my changes.
• All new and existing tests passed.

Notes

Here are some of the issues blocking further development:

• Mesh data is uploaded to the GPU as soon as it is deserialized, we don't store it in CPU mem.
• Deserialization happens in bulk, we can't just read mesh data from disk. We need to somehow wait for the mesh's buffers to be initialized and retrieve the data used to create those.
• Master cannot yet easily extract mesh data at runtime from the GPU, see reading buffers without command list
