gccrs: Add get_locus function for abstract class MetaItemInner.

Browse Source 
This commit adds virtual function get_locus to base class MetaItemInner,
which is helpful when we need to print  diagnostics on some sub-classes of
MetaItemInner.

gcc/rust/ChangeLog:

	* ast/rust-ast.h: Add get_locus method.
	* ast/rust-expr.h: Likewise.
	* ast/rust-macro.h: Likewise.
