Change query proc macro to be more rust-analyzer friendly

[Zoxc]

This changes the query proc macro to be more rust-analyzer friendly.

• Types in the macro now have a proper span
• Some functions have their span hidden so they don't show up when hovering over the query name
• Added a hint on the provider field on how to find providers. That is shown when hovering over the query name
• Linked query name to the provider field on all queries, not just ones with caching
• Added tooltip for the query modifiers by linking to the new types in rustc_middle:::query::modifiers

I might take a look at this PR but I'm not sure if I'm the right person since I've disabled proc-macro expansion for r-l/r checkouts to avoid rust analyzer frying my machine, so I can't really experiment with this patch locally.

I was initially worried about this breaking hover-docs and find-all-references (for the query method) from queries.rs, but it turns out that those already don't work. 😅

(They do appear to still work for calls to the query method.)

I'm not seeing any tooltips for the query modifiers on my machine; hovering over the modifier name in the query body doesn't show anything for me.

Is it working for you?

Is it working for you?

Yeah, on rust-analyzer 0.3.2786-standalone (c75729db68 2026-02-09). Do you see any other changes? It takes a while to compile the proc macros with rust-analyzer, so make sure its idle.

I updated r-a and hovering on modifiers works for me now, so it must have been sensitive to a recent change. 👍

Looks good, thanks.
