Add COMPILE_OPTIONS target property. This method reads generator expressions from the COMPILE_OPTIONS target property, as well as INTERFACE_COMPILE_OPTIONS from linked dependents.

Add generator expressions for compiler versions. New generator expressions allow retrieval of the version per language, as well as equality comparison.

Escape target flags taken from COMPILE_OPTIONS Factor appending of individual flags out into an AppendFlagEscape method in cmLocalGenerator and teach it to use EscapeForShell. Update all COMPILE_OPTIONS handling to use AppendFlagEscape. Override the method in the Xcode generator to use its custom escape implementation. Teach the CompileOptions test to add an option that requires escaping everywhere instead of just with the GNU tools.

Makefile: Handle '#' in COMPILE_OPTIONS (#15070) Teach the Makefile generators to escape '#' characters on the right hand side of variable assignments in flags.make. This is needed for flags like '-Wno-error=#warnings'. Otherwise the make tool treats them as comments and leaves them out of the _FLAGS variable value. Add a case to the CompileOptions test covering '#' in a COMPILE_OPTIONS value, at least on compilers where it is known to be supported.
