rustc: Fix two custom attributes with custom derive This commit fixes an issue where multiple custom attributes could not be fed into a custom derive in some situations with the `use_extern_macros` feature enabled. The problem was that the macro expander didn't consider that it was making progress when we were deducing that attributes should be lumped in with custom derive invocations. The fix applied here was to track in the expander if our attribute is changing (getting stashed away elsewhere and replaced with a new invocation). If it is swapped then it's considered progress, otherwise behavior should remain the same. Closes #52525 |

The syntax crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), parser, pretty-printer,
lexer, macro expander, and utilities for traversing ASTs.
For more information about how these things work in rustc, see the rustc guide:
