mesa/formatquery: Added queries related to image textures
From the ARB_internalformat_query2 specification: "- IMAGE_TEXEL_SIZE: The size of a texel when the resource when used as an image texture is returned in <params>. This is the value from the /Size/ column in Table 3.22. If the resource is not supported for image textures, or if image textures are not supported, zero is returned. - IMAGE_COMPATIBILITY_CLASS: The compatibility class of the resource when used as an image texture is returned in <params>. This corresponds to the value from the /Class/ column in Table 3.22. The possible values returned are IMAGE_CLASS_4_X_32, IMAGE_CLASS_2_X_32, IMAGE_CLASS_1_X_32, IMAGE_CLASS_4_X_16, IMAGE_CLASS_2_X_16, IMAGE_CLASS_1_X_16, IMAGE_CLASS_4_X_8, IMAGE_CLASS_2_X_8, IMAGE_CLASS_1_X_8, IMAGE_CLASS_11_11_10, and IMAGE_CLASS_10_10_10_2, which correspond to the 4x32, 2x32, 1x32, 4x16, 2x16, 1x16, 4x8, 2x8, 1x8, the class (a) 11/11/10 packed floating-point format, and the class (b) 10/10/10/2 packed formats, respectively. If the resource is not supported for image textures, or if image textures are not supported, NONE is returned. - IMAGE_PIXEL_FORMAT: The pixel format of the resource when used as an image texture is returned in <params>. This is the value from the /Pixel format/ column in Table 3.22. If the resource is not supported for image textures, or if image textures are not supported, NONE is returned. - IMAGE_PIXEL_TYPE: The pixel type of the resource when used as an image texture is returned in <params>. This is the value from the /Pixel type/ column in Table 3.22. If the resource is not supported for image textures, or if image textures are not supported, NONE is returned."
