u_format: Define tests for r3g3b2 formats and fix BE swizzles for them.

Browse Source 
These tests passed for LE, and the BE channel ordering specified obviously
didn't fit the pattern of the other BE formats (channels are listed
right-to-left in the BE columns for historical reasons).

Note that we can't write pure-integer format tests in u_format_tests.c
currently.
