mesa/st: Handle all 10 bpc types in st_choose_format
Only GL_UNSIGNED_INT_2_10_10_10_REV was handled, add GL_UNSIGNED_INT_10_10_10_2 & GL_UNSIGNED_INT_10_10_10_2_OES.
This makes sure that if the Gallium driver doesn't support the exact corresponding format, another 10 bpc format is tried before an 8 bpc one as a fallback.
Fixes the mutter test cogl-test-offscreen-texture-formats with iris.
