Testcase: https://github.com/elad335/myps3tests/tree/master/rsx_tests/write%20output%20mask
This testcase tests what happens on a write to ones to reserved of color mask register
It does this by iterating and ORis valid masks with a single reserved bit at a time, for completeness it also tests it with valid bit masks as well and examines buffer state.
Results: writes with reserved bits set are being ignored by RSX.
Fixes the colors in #13101.
Fixes #10530.
Fixes #10533.
