Add optional support for using the system libicu

Is it required to remove the font/layout dir to use the system version?
I would expect USE_EXTERNAL_ICU_LE=true would add an exclude for that
directory to SetupNativeCompilation,BUILD_LIBFONTMANAGER.
If you expect to delete the source tree on your side, why not have
configure check for the existence of the font/layout directory to
determine the default behavior for system vs bundled?
It seems you forgot to add USE_EXTERNAL_ICU_LE to spec.gmk.in.
Are ICU_LE_CFLAGS and ICE_LE_LIBS supposed to be empty?
