fix: lifetime length are not added in count of params in highlight
I found these two instances easily but I wonder how many such instances are there.
Fixes#16958
Revert to the crates.io version of rustc_pattern_analysis
The API hasn't fully settled yet, and there's an extra wrinkle with `IdxContainer` which blocked the [subtree update](https://github.com/rust-lang/rust/pull/122981). Let's just keep using the crates.io version for a bit longer.

Handle panicking like rustc CTFE does
Instead of using `core::fmt::format` to format panic messages, which may in turn panic too and cause recursive panics and other messy things, redirect `panic_fmt` to `const_panic_fmt` like CTFE, which in turn goes to `panic_display` and does the things normally. See the tests for the full call stack.
The tests don't work yet, I probably missed something in minicore.
fixes#16907 in my local testing, I also need to add a test for it
fix: Prevent stack overflow in recursive const types
In the evaluation of const values of recursive types certain declarations could cause an endless call-loop within the interpreter (hir-ty’s create_memory_map), which would lead to a stack overflow.
This commit adds a check that prevents values that contain an address in their value (such as TyKind::Ref) from being allocated at the address they contain.
The commit also adds a test for this edge case.

fix: Some file watching related vfs fixes
Fixes https://github.com/rust-lang/rust-analyzer/issues/15554, additionally it seems that client side file watching was broken on windows this entire time, this PR switches `DidChangeWatchedFilesRegistrationOptions` to use relative glob patterns which do work on windows in VSCode.
Have Derive Attribute share a token tree with it's proc macros.
The goal of this PR is to stop creating a token tree for each derive proc macro.
This is done by giving the derive proc macros an id to its parent derive element.
From running the analysis stat on the rust analyzer project I did see a small memory decrease.

Currently this breaks the expansion for the actual derive attribute.
## TODO
- [x] Pick a better name for the function `smart_macro_arg`
fix: Fix projects depending on `rustc_private` hanging
If loading the root fails, we'll hang up in this loop as we never inserted the entry that asserts we already visited a package. This fixes that
