Rebase of #5119 authored by
@evanrittenhouse with additional refinements.

## Changes

- Adds `--unsafe-fixes` / `--no-unsafe-fixes` flags to `ruff check`
- Violations with unsafe fixes are not shown as fixable unless opted-in
- Fix applicability is respected now
    - `Applicability::Never` fixes are no longer applied
    - `Applicability::Sometimes` fixes require opt-in
    - `Applicability::Always` fixes are unchanged
- Hints for availability of `--unsafe-fixes` added to `ruff check`
output

## Examples

Check hints at hidden unsafe fixes
```
❯ ruff check example.py --no-cache --select F601,W292
example.py:1:14: F601 Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 1 fixable with the `--fix` option (1 hidden fix can be enabled with the `--unsafe-fixes` option).
```

We could add an indicator for which violations have hidden fixes in the
future.

Check treats unsafe fixes as applicable with opt-in
```
❯ ruff check example.py --no-cache --select F601,W292 --unsafe-fixes
example.py:1:14: F601 [*] Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 2 fixable with the --fix option.
```

Also can be enabled in the config file

```
❯ cat ruff.toml
unsafe-fixes = true
```

And opted-out per invocation

```
❯ ruff check example.py --no-cache --select F601,W292 --no-unsafe-fixes
example.py:1:14: F601 Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 1 fixable with the `--fix` option (1 hidden fix can be enabled with the `--unsafe-fixes` option).
```

Diff does not include unsafe fixes
```
❯ ruff check example.py --no-cache --select F601,W292 --diff
--- example.py
+++ example.py
@@ -1,2 +1,2 @@
 x = {'a': 1, 'a': 1}
-print(('foo'))
+print(('foo'))
\ No newline at end of file

```

Unless there is opt-in
```

+x = {'a': 1, 'a': 1}

```

#7790 will improve the diff
messages following this pull request

Similarly, `--fix` and `--fix-only` require the `--unsafe-fixes` flag to
apply unsafe fixes.
