Meta+Userland: Add ENABLE_USERSPACE_COVERAGE_COLLECTION CMake option

Browse source 
This option sets -fprofile-instr-generate -fcoverage-mapping for Clang
builds only on almost all of Userland. Loader and LibTimeZone are
exempt. This can be used for generating code coverage reports, or even
PGO in the future.
