Add ability to remap file names in __FILE__, etc (PR other/70268)
This commit adds the -fmacro-prefix-map option that allows remapping of file
names in __FILE__, __BASE_FILE__, and __builtin_FILE(), similar to how
-fdebug-prefix-map allows to do the same for debug information.
Additionally, it adds -ffile-prefix-map which can be used to specify both
mappings with a single option (and, should we need to add more -f*-prefix-map
options in the future, those as well).
