Subject: tools: Unify top-level quiet infrastructure

Commit f2868b1a66d4f40f ("perf tools: Expose quiet/verbose variables in
Makefile.perf") moved the quiet infrastructure out of
tools/build/Makefile.build and into the top-level Makefile.perf file so
that the quiet infrastructure could be used throughout perf and not just
in Makefile.build.

Extract out the quiet infrastructure into Makefile.include so that it
can be leveraged outside of perf.

Fixes: f2868b1a66d4f40f ("perf tools: Expose quiet/verbose variables in Makefile.perf")
