docs: update MESA_DEBUG envvar documentation.
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.
v2 (Brian Paul):
* MESA_DEBUG accepts a comma-separated list of parameters.
* Clarify how MESA_DEBUG behaves with mesa debug and release builds.
* Updated wording.
v3: Better wording for one paragraph (Brian Paul)
