Add support for EXT_texture_compression_bptc

After validation, the enums are simply forwarded to the native
drivers. The BPTC formats are supported on both OpenGL and D3D.

The included test coverage covers the API quite well, but only has
basic coverage for correct decoding of texture data. More coverage for
texture data could be added later.
