lib: cpp: Introduce FULL_LIBCPP_SUPPORTED similar to C version

Introduce Kconfig symbol FULL_LIBCPP_SUPPORTED that is similar to the C version FULL_LIBC_SUPPORTED. This way we can utilize the same pattern in tests and samples to filter for when a full libc++ is needed. Signed-off-by: Kumar Gala <[email protected]>
