internal: Reply to requests with defaults when vfs is still loading
There is no reason for us to hit the database with queries when we certainly haven't reached a stable state yet. Instead we just reply with default request results until we are in a state where we can do meaningful work. This should save us from wasting resources while starting up at worst, and at best save us from creating query and interning entries that are non-meaningful which ultimately just end up wasting memory.
internal: Optimize the usage of channel senders
Used `Sender` directly instead of a boxed closure. There is no need to use the boxed closure. This also allows the caller to decide to do something other than `unwrap` (not a fan of it BTW).
Reuse recursion limit as expansion limit
A configurable recursion limit was introduced by looking at the recursion_limit crate attribute. Instead of relying on a global constant we will reuse this value for expansion limit as well.

feat: Implement TAIT and fix ATPIT a bit
Closes#16296 (Commented on the issue)
In #16852, I implemented ATPIT, but as I didn't discern ATPIT and other non-assoc TAIT, I guess that it has been working for some TAITs.
As the definining usage of TAIT requires it should be appear in the Def body's type(const blocks' type annotations or functions' signatures), this can be done in simlilar way with ATPIT
And this PR also corrects some defining-usage resolution for ATPIT

internal: Move and split flycheck crate into rust-analyzer main crate
The crate no longer is about flychecking, it mainly hosts common command process handling shared by flycheck, test explorer and now project discovery. This re-organizes that into the main crate.
Improve crate manifest of 'syntax-bridge', adding missing `[package.repository]` and `[package.description]` fields
This is a follow-up of https://github.com/rust-lang/rust-analyzer/pull/17745, specifically [this comment](https://github.com/rust-lang/rust-analyzer/pull/17745#issuecomment-2271102382) by `@lnicola.`
It refines the manifest of the newly added 'syntax-bridge' crate, adding a `[package.repository]` as `workspace = true` and changes the existing `[package.description]` from "TBD" to a more useful description.
