Add external projects only CFlags option

Every time the toolchain adds a new warning, we had to suppress the
warning in every external projects that violates it, or disable it
globally -- which we end up doing most of the time since the first
option is way too time consuming.

Add a separate cflags option for external projects and move existing
-Wno-* flags there so that we can enforce better code quality for
internal projects.

TODO: Move more -Wno-* flags to ClangExtraExternalCflags

Test: m checkbuild
