Add tests of all macros used by libyuv public headers
When a 1 step conversion is added, a 2 step test can compare
the old 2 step method to the 1 step. A 1 step unittest is
also added which compares C to SIMD. Making the 2 step
conversions measure performance of the 2 steps allows the
old 2 step performance to be compared to 1 step.
All macros used in public headers are added to an ifdef test.
Showing them in a unittest allows some diagnostics when
a test is failing.
