Auto merge of #130337 - BoxyUwU:anon_const_macro_call, r=camelid
Fix anon const def-creation when macros are involved take 2
Fixes #130321
There were two cases that #129137 did not handle correctly:
- Given a const argument `Foo<{ bar!() }>` in which `bar!()` expands to `N`, we would visit the anon const and then visit the `{ bar() }` expression instead of visiting the macro call. This meant that we would build a def for the anon const as `{ bar!() }` is not a trivial const argument as `bar!()` is not a path.
- Given a const argument `Foo<{ bar!() }>` is which `bar!()` expands to `{ qux!() }` in which `qux!()` expands to `N`, it should not be considered a trivial const argument as `{{ N }}` has two pairs of braces. If we only looked at `qux`'s expansion it would *look* like a trivial const argument even though it is not. We have to track whether we have "unwrapped" a brace already when recursing into the expansions of `bar`/`qux`/any macro

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
