gccrs: Rename libproc_macro to libproc_macro_internal

The name was a bit misleading since libproc_macro is a rust library that
should we should be able to link against some rust code. This cpp
library was the layer below the libproc_macro library, the "real" gcc
libproc_macro act as a translation layer for the internal library.

gcc/rust/ChangeLog:

	* expand/rust-macro-expand.h: Change include directive with the
	new name.

	* util/rust-token-converter.cc: Remove useless include
	directive.
