silent, flush, incomplete_tex and incomplete_fbo flags were not
documented (see src/mesa/main.debug.c for more info).
FP is not checked anymore.

Didn't know about the flush option for MESA_DEBUG until Grazvydas Ignotas
mentioned it on a freedesktop bug comment (thanks), so this patch documents
it.
CCing Eric Anholt because MESA_DEBUG=flush and VC4_DEBUG=always_flush seems
to have basically the same purpose, in case one needs to be removed.
CCing Brian because he added the incomplete_tex and incomplete_fbo flags
with commit 93bcf7, and I just added a really basic documentation line for
those options, just in case it is worth more details.
Note that I assume that all the specific flags for MESA_DEBUG are handled
at debuc.c:set_debug_flags. As it is not taking into account FP, Im also
dropping the FP line with this patch.
