expand: Rename AttrVisitor -> CfgStrip

Since the expansion and stripping phase are now separated, it does not
make sense to keep AttrVisitor named AttrVisitor. Furthermore, the visitor
is already very complex, with a heavy mental load (erasing iterators,
rearranging them, performing cfg-expansion, etc) so further attribute
handling should probably happen in rust-attribute-checker.h

gcc/rust/ChangeLog:

	* Make-lang.in: Rename rust-asttribute-visitor.o -> rust-cfg-strip.o
	* expand/rust-attribute-visitor.cc: Moved to...
	* expand/rust-cfg-strip.cc: ...here.
	* expand/rust-attribute-visitor.h: Moved to...
	* expand/rust-cfg-strip.h: ...here.
	* expand/rust-macro-expand.cc: Fix include of rust-attribute-visitor.h
	* expand/rust-macro-builtins.cc: Likewise.
	* rust-session-manager.cc (Session::expansion): Call CfgStrip instead of
	AttrVisitor.
