Sema seems to be flagging inout expressions (e.g. &foo) in expression macros as invalid, setting up a catch 22 where Sema emits an error when a parameter has the '&' sigil and type checking fails when it doesn't.
This resolves the issue by allowing inout expressions inside macro expansion expressions.
Resolves #82369.
