mesa/formatquery: Added texture view related queries
From the ARB_internalformat_query2 specification:
"- TEXTURE_VIEW: The support for using the resource with the TextureView
command is returned in <params>.
Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
If the resource or operation is not supported, NONE is returned.
- VIEW_COMPATIBILITY_CLASS: The compatibility class of the resource when
used as a texture view is returned in <params>. The compatibility
class is one of the values from the /Class/ column of Table 3.X.2. If
the resource has no other formats that are compatible, the resource
does not support views, or if texture views are not supported, NONE is
returned."
