feat(cmakev2/utilities): add __get_compile_options helper

Browse Source 
Gather the compilation options from COMPILE_OPTIONS, C_COMPILE_OPTIONS,
CXX_COMPILE_OPTIONS, and ASM_COMPILE_OPTIONS build properties into a
single list using generator expressions. This list can then be used with
the target_compile_options call.
