[gn] Don't use cc_wrapper for link steps

I'm aware of two uses for cc_wrapper:
 - Goma support for linking is experimental, and normally just falls
   back to the local compiler.
 - ccache site says it always falls back to the real compiler for
   linking. https://ccache.dev/

The msvc toolchain already does not use cc_wrapper for linking; this
change removes it for gcc_like_toolchain. This matches Chromium, e.g.
