The variables to make builds silent/verbose live inside
tools/build/Makefile.build. Move those variables to the top-level
Makefile.perf to be generally available.

Some shell tests compete for resources and so can't run with other
tests, tag such tests. The "(exclusive)" stems from shared/exclusive
to describe how the tests run as if holding a lock.

Running shellcheck on some of the shell scripts, throws
below warning on shellcheck v0.6. Example:
In tests/shell/coresight/asm_pure_loop.sh line 14:
DATA="$DATD/perf-$TEST-$DATV.data"
^---^ SC2153: Possible misspelling: DATD may not be assigned, but DATA is.
Here, DATD is exported from "lib/coresight.sh" and this
warning can be ignored. Use "shellcheck disable=" to ignore
this check.

arm64 ASM with no libc usage to ensure it is the same exact binary/code
every time so it can also be re-used for many uses. It just loops for a

This adds the initial build infrastructure (makefiles maintainers
information) for adding follow-on tests for CoreSight.
Committer notes:
Remove the installation of tests/shell/coresight/*.sh, as there are no
files there yet and thus, at this point, make install fails.
Use $(QUIET_CLEAN) to avoid having extraneous output in the 'make clean'
output.
Also use @$(MAKE) in tools/perf/tests/shell/coresight/Makefile as $(Q)
is not turning into @ when V=1 isn't used, i.e. in the default case it
is not being quiet.
The >/dev/null in the all for tools/perf/tests/shell/coresight/Makefile
is to avoid this:
make[4]: Nothing to be done for 'all'.
make[4]: Nothing to be done for 'all'.
make[4]: Nothing to be done for 'all'.
DESCEND plugins
GEN /tmp/build/perf/python/perf.so
make[4]: Nothing to be done for 'all'.
INSTALL trace_plugins
On !arm64 where nothing is done on the main target for
tools/perf/tests/shell/coresight/*/Makefile.
