mesa/teximage: return the base internal format of the ASTC formats
This is necesary to initialize the gl_texture_image struct.
From the KHR_texture_compression_astc_ldr spec:
"Added to Section 3.8.6, Compressed Texture Images
Add the tokens specified above to Table 3.16, Compressed Internal Formats.
In all cases, the base internal format will be RGBA. The encoding allows
images to be encoded with fewer channels, but this is always presented as
RGBA to the sampler."
v2. use _mesa_is_astc_format().
