Rollup merge of #153326 - Zalathar:query-modifiers, r=nnethercote
Make `rustc_with_all_queries!` pass query modifiers as named values
This PR is a bold overhaul of how the proc-macro in `rustc_macros::query` passes query modifiers to the callback macros in `rustc_middle` and `rustc_query_impl`.
The existing approach passes modifiers as a list that looks like `[(arena_cache), (no_hash)]`. That style requires a family of helper macros (`if_arena_cache!`, `if_no_hash!`) to check for modifiers when consuming the query list.
This PR changes the proc-macro to instead pass modifiers like this:
```text
{
anon: false,
arena_cache: true,
cache_on_disk: false,
...
}
```
This style allows each of the callback macros to deconstruct the modifier list in a relatively straightforward way, by binding the true/false literals to variables like `$arena_cache:literal`.
One of the big advantages of this style is that we can write things like `#[cfg($arena_cache)]` and `#[cfg(not($arena_cache))]` to select blocks of code, eliminating the need for the `if_arena_cache!` family of helper macros.
In follow-up PRs, we can also try to take advantage of the new modifier style to pass richer information for some modifiers, such as `desc` or `cache_on_disk_if`. That could potentially make it more reasonable to get rid of the `_description_fns` and `_cache_on_disk_if_fns` modules, as proposed in https://github.com/rust-lang/rust/pull/153065.
