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." Reviewed-by: Dave Airlie <[email protected]>
