change AccessLevels representation
Part of RFC (https://github.com/rust-lang/rust/issues/48054). This patch implements effective visibility table with basic methods and change AccessLevels table representation according to it.
r? ``@petrochenkov``

On later stages, the feature is already stable.
Result of running:
rg -l "feature.let_else" compiler/ src/librustdoc/ library/ | xargs sed -s -i "s#\\[feature.let_else#\\[cfg_attr\\(bootstrap, feature\\(let_else\\)#"

Simplify visitors more
A successor to #100392.
r? `@cjgillot`

The `visit_path_segment` method of both the AST and HIR visitors has a
`path_span` argument that isn't necessary. This commit removes it.
There are two very small and inconsequential functional changes.
- One call to `NodeCollector::insert` now is passed a path segment
identifier span instead of a full path span. This span is only used in
a panic message printed in the case of an internal compiler bug.
- Likewise, one call to `LifetimeCollectVisitor::record_elided_anchor`
now uses a path segment identifier span instead of a full path span.
This span is used to make some `'_` lifetimes.

rustc: Parameterize `ty::Visibility` over used ID
It allows using `LocalDefId` instead of `DefId` when possible, and also encode cheaper `Visibility<DefIndex>` into metadata.

`BindingAnnotation` refactor
* `ast::BindingMode` is deleted and replaced with `hir::BindingAnnotation` (which is moved to `ast`)
* `BindingAnnotation` is changed from an enum to a tuple struct e.g. `BindingAnnotation(ByRef::No, Mutability::Mut)`
* Associated constants added for convenience `BindingAnnotation::{NONE, REF, MUT, REF_MUT}`
One goal is to make it more clear that `BindingAnnotation` merely represents syntax `ref mut` and not the actual binding mode. This was especially confusing since we had `ast::BindingMode`->`hir::BindingAnnotation`->`thir::BindingMode`.
I wish there were more symmetry between `ByRef` and `Mutability` (variant) naming (maybe `Mutable::Yes`?), and I also don't love how long the name `BindingAnnotation` is, but this seems like the best compromise. Ideas welcome.

Remove generics_def_id_map from the resolver.
This is internal state for lowering. This does not belong in the resolver.

optimization of access level table construction
Refactoring which was mentioned in #87487

Remove EntryKind from metadata.
This PR continues the refactor of metadata emission to be more systematic, iterating on definitions and filtering based on each definition's `DefKind`. This allows to remove the large `EntryKind` enum, replaced by linear tables in metadata.

Fix a bunch of typo
This PR will fix some typos detected by [typos].
I only picked the ones I was sure were spelling errors to fix, mostly in
the comments.

Remove separate indexing of early-bound regions
~Based on https://github.com/rust-lang/rust/pull/99728.~
This PR copies some modifications from https://github.com/rust-lang/rust/pull/97839 around object lifetime defaults.
These modifications allow to stop counting generic parameters during lifetime resolution, and rely on the indexing given by `rustc_typeck::collect`.

sugg: suggest the usage of boolean value when there is a typo in the keyword
Fixes https://github.com/rust-lang/rust/issues/100686
This adds a new suggestion when there is a well-known typo
With the following program
```rust
fn main() {
let x = True;
}
```
Now we have the following suggestion
```
error[E0425]: cannot find value `True` in this scope
--> test.rs:2:13
|
2 | let x = True;
| ^^^^ not found in this scope
|
help: you may want to use a bool value instead
|
2 | let x = true;
| ~~~~
error: aborting due to previous error
```
