gccrs: typecheck: Separate assemble_builtin_candidate in two

This paves the way for adding trait bounds that aren't necessarily Sized.

gcc/rust/ChangeLog:

	* typecheck/rust-tyty-bounds.cc (TypeBoundsProbe::add_trait_bound): New function.
	* typecheck/rust-hir-type-bounds.h: Declare it.
	(TypeBoundsProbe::assemble_builtin_candidate): Call into add_trait_bound.
