Rollup merge of #145399 - estebank:resolve-error-wording-2, r=petrochenkov
Unify wording of resolve error
Remove "failed to resolve" from the main error message and use the same format we use in other resolution errors "cannot find `name`":
```
error[E0433]: cannot find `nonexistent` in `existent`
--> $DIR/custom_attr_multisegment_error.rs:5:13
|
LL | #[existent::nonexistent]
| ^^^^^^^^^^^ could not find `nonexistent` in `existent`
```
The intent behind this is to end up with all resolve errors eventually be on the form of
```
error[ECODE]: cannot find `{NAME}` in {SCOPE}
--> $DIR/file.rs:5:13
|
LL | #[existent::nonexistent]
| ^^^^^^^^^^^ {SPECIFIC LABEL}
```
A category of errors that is interest are those that involve keywords. For example:
```
error[E0433]: cannot find `Self` in this scope
--> $DIR/issue-97194.rs:2:35
|
LL | fn bget(&self, index: [usize; Self::DIM]) -> bool {
| ^^^^ `Self` is only available in impls, traits, and type definitions
```
and
```
error[E0433]: cannot find `super` in this scope
--> $DIR/keyword-super.rs:2:9
|
LL | let super: isize;
| ^^^^^ there are too many leading `super` keywords
```
For these the label provides the actual help, while the message is less informative beyond telling you "couldn't find `name`".
This is an off-shoot of https://github.com/rust-lang/rust/pull/126810 and https://github.com/rust-lang/rust/pull/128086, a subset of the intended changes there with review comments applied.

Improve write! and writeln! error when called without destination
Fixesrust-lang/rust#152493
Adds catch-all arms to `write!` and `writeln!` macros so that calling them without a destination (e.g., `write!("S")` instead of `write!(f, "S")`) gives a clear error instead of the cryptic "unexpected end of macro invocation" pointing at macro internals.

`const` blocks as a `mod` item
Tracking issue: rust-lang/rust#149226
This adds support for writing `const { ... }` as an item in a module. In the current implementation, this is a unique AST item that gets lowered to `const _: () = const { ... };` in HIR.
rustfmt support included.
TODO:
- `pub const { ... }` does not make sense (see rust-lang/rust#147136). Reject it. Should this be rejected by the parser or smth?
- Improve diagnostics (preferably they should not mention the fake `_` ident).
The problem is that when a macro expand to `compile_error!` because
its input is malformed, the actual error message from the
`compile_error!` might be hidden in a long list of other messages about
using items that should have otherwise been generated by the macro.
So suppress error about missing items in that module.

Currently all core and std macros are automatically added to the prelude
via #[macro_use]. However a situation arose where we want to add a new macro
`assert_matches` but don't want to pull it into the standard prelude for
compatibility reasons. By explicitly exporting the macros found in the core and
std crates we get to decide on a per macro basis and can later add them via
the rust_20xx preludes.
Fix macro_metavar_expr_concat behavior with nested repetitions
**The Bug**: The `${concat(...)}` expression was using the wrong loop index when inside nested repetitions (like optional groups), causing it to get "stuck" on the first element and generate duplicate code.
**The Fix**: Updated `metavar_expr_concat` in `transcribe.rs` to correctly search the repetition stack (`tscx.repeats`) for the target variable instead of blindly using the last index.
**Tests**:
Added `tests/ui/macros/concat-nested-repetition.rs.`

Use annotate-snippet as default emitter on stable
This is implementation of https://github.com/rust-lang/rust/issues/149932
Now, after MCP was accepted, we can use annotate-snippet as default emitter for errors, that means that we not longer need of previous emitter, so this PR removed previous emitter and makes annotate-snippet new default one both on stable and nightly
(this PR does not remove a code of previous emitter it just removes a `Default` option of `HumanReadableErrorType` enum, and keeping only `HumanReadableErrorType::AnnotateSnippet` as it now uses by default)
