Rollup merge of #144369 - joshtriplett:mbe-expr-semi-deny-by-default, r=petrochenkov
Upgrade semicolon_in_expressions_from_macros from warn to deny
This is already warn-by-default, and a future compatibility warning (FCW) that warns in dependencies. Upgrade it to deny-by-default, as the next step towards hard error.
