virgl: stricter usage of compressed 3d textures
Using RGTC, ETC1, ETC2 or S3TC for 3D-textures isn't alowed by any of
OpenGL 4.6, OpenGL ES 3.2, ARB_texture_compression_rgtc,
EXT_texture_compression_rgtc, OES_compressed_ETC1_RGB8_texture,
S3_s3tc or EXT_texture_compression_s3tc specifications.
So let's not allow any of those compressed 3d-textures at all. It's not
going to work once it hits the OpenGL driver in virglrenderer.
