Rollup merge of #145590 - nnethercote:ModKind-Inline, r=petrochenkov

Prevent impossible combinations in `ast::ModKind`.

`ModKind::Loaded` has an `inline` field and a `had_parse_error` field. If the `inline` field is `Inline::Yes` then `had_parse_error` must be `Ok(())`.

This commit moves the `had_parse_error` field into the `Inline::No` variant. This makes it impossible to create the nonsensical combination of `inline == Inline::Yes` and `had_parse_error = Err(_)`.
