use "bootstrap" instead of "rustbuild" in comments and docs
Let's stick with the single name "bootstrap" to refer to the bootstrap project to avoid confusion. This should make it clearer, especially for new contributors.

feat: do not add new enum if it already exists
## Summary
This PR introduces a check for the existence of another enum within the current scope, and if it exist, we skip `add_enum_def`.
## Why?
Currently, when using the `bool_to_enum` assist more than once, it is possible to add multiple enum definitions. For example, the following snippet,
```rs
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
fn main() {
let a = Bool::True;
let b = true;
println!("Hello, world!");
}
```
will be transformed into,
```rs
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
fn main() {
let a = Bool::True;
let b = Bool::True;
println!("Hello, world!");
}
```
This can be annoying for users to clean up.

Add `f16` and `f128` support
Adds `f16` and `f128` support, using the `rustc_apfloat` library (also used by `rustc`) for parsing/arithmetic/displaying since the types aren't stable yet so can't be used by rust-analyzer itself.
Issue: #17451

feat: add inlay hints for generic parameters
fixes #11091
By default, only hints for const generic parameters are shown, and this can be configured through `rust-analyzer.inlayHints.genericParameterHints.enable`.
Probably needs more testing.

- unrelated to the PR but I wanted to change this in #17467

fix: Fix double rounding of `f32` literals
Fixes #17556 by delaying parsing until the type is known. Also adds a test to check the issue is fixed.

Make casts of pointers to trait objects stricter
This is an attempt to `fix` https://github.com/rust-lang/rust/issues/120222 and https://github.com/rust-lang/rust/issues/120217.
This is done by adding restrictions on casting pointers to trait objects.
Before this PR the rules were as follows:
> When casting `*const X<dyn A>` -> `*const Y<dyn B>`, principal traits in `A` and `B` must refer to the same trait definition (or no trait).
With this PR the rules are changed to
> When casting `*const X<dyn Src>` -> `*const Y<dyn Dst>`
> - if `Dst` has a principal trait `DstP`,
> - `Src` must have a principal trait `SrcP`
> - `dyn SrcP` and `dyn DstP` must be the same type (modulo the trait object lifetime, `dyn T+'a` -> `dyn T+'b` is allowed)
> - Auto traits in `Dst` must be a subset of auto traits in `Src`
> - Not adhering to this is currently a FCW (warn-by-default + `FutureReleaseErrorReportInDeps`), instead of an error
> - if `Src` has a principal trait `Dst` must as well
> - this restriction will be removed in a follow up PR
This ensures that
1. Principal trait's generic arguments match (no `*const dyn Tr<A>` -> `*const dyn Tr<B>` casts, which are a problem for [#120222](https://github.com/rust-lang/rust/issues/120222))
2. Principal trait's lifetime arguments match (no `*const dyn Tr<'a>` -> `*const dyn Tr<'b>` casts, which are a problem for [#120217](https://github.com/rust-lang/rust/issues/120217))
3. No auto traits can be _added_ (this is a problem for arbitrary self types, see [this comment](https://github.com/rust-lang/rust/pull/120248#discussion_r1463835350))
Some notes:
- We only care about the metadata/last field, so you can still cast `*const dyn T` to `*const WithHeader<dyn T>`, etc
- The lifetime of the trait object itself (`dyn A + 'lt`) is not checked, so you can still cast `*mut FnOnce() + '_` to `*mut FnOnce() + 'static`, etc
- This feels fishy, but I couldn't come up with a reason it must be checked
The diagnostics are currently not great, to say the least, but as far as I can tell this correctly fixes the issues.

Hi I'm very new to rust-analyzer and not sure how the review process are. Can somebody take a look at this PR? thanks!

Also mark InferenceResult::has_errors flag when there are error types
Should work around https://github.com/rust-lang/rust-analyzer/issues/15090#issuecomment-2211647133

fix: Fix runnables being incorrectly constructed
I've misunderstood parts of the code here which caused runnables to arbitrarily break :) (I have yet to understand the conditions that made them break though, there is some odd caching involved I feel like ...)

internal: Clean up runnable lsp extension
This feels like a natural addition to me, and also allows us to drop the expect-test hardcoding from the extension. Additionally, `cargoExtraArgs` is pointless, all the client will do is merge it with `cargoArgs` so the server can do that instead of delegating that to the client.
