Add captures for ClosureExprInnerTyped with nr2

Captures were only processed for regular ClosureExprInner.

gcc/rust/ChangeLog:

	* resolve/rust-late-name-resolver-2.0.cc (Late::visit): Add
	ClosureExprInnerTyped visit implementation.
	(add_captures): Add a function to avoid code duplication.
	* resolve/rust-late-name-resolver-2.0.h: Add function prototype.
