[asan] Add CMake hook to override shadow scale in compiler_rt
Allow user to override shadow scale in compiler_rt by passing
-DCOMPILER_RT_ASAN_SHADOW_SCALE=n to CMake. Propagate the override
shadow scale value via a compiler define to compiler-rt and asan
tests. Tests will use the define to partially disable unsupported
tests. Set "-mllvm -asan-mapping-scale=<n>" for compiler_rt tests.
