gccrs: ast: dump literals correctly

This commit fixes printing of literals based on their
type.

Previous implementation printed literals the same, regardless
their type. Now we are printing:
  * int, float, bool don't require special printing
  * char        -> '<char>'
  * string      -> "<string>"
  * byte        -> b'<byte>'
  * byte_string -> b"<byte_string>"

gcc/rust/ChangeLog:

	* ast/rust-ast-dump.cc (Dump::visit):
	print literals based on their type.
