Title: TextureProcessor Fixes and Tests

This PR adds some fixes to the `TextureProcessor` as well as the start of some unit tests for it.

- Fixed mipmap generation from occurring twice on compressed textures.
- Fixed incorrect defaults in `TextureProcessor`.
- `Texture2DContent` was not correctly initializing the `Faces`.
- Fixed incorrect implicit operator in `MipmapChain`.
- Implemented `overwriteExistingMipmaps` in `TextureContent.GenerateMipmaps`.
