gccrs: dump: Remove tokenstream dump

This dump will soon replace ast-pretty print and is hence no longer
required.

gcc/rust/ChangeLog:

	* rust-session-manager.cc (Session::enable_dump): Remove
	tokenstream dump.
	(Session::compile_crate): Likewise.
	(Session::dump_tokenstream): Likewise.
	* rust-session-manager.h (struct CompileOptions): Likewise.
