## Summary
Implement `write-whole-file` (`FURB103`), part of #1348. This is largely
a copy and paste of `read-whole-file` #7682.
## Test Plan
Text fixture added.

## Summary
The `add_rule.py` script would create a test case that pointed to a file
that didn't exist when the linter is set to `"pylint"`. This PR fixes
that.
## Test Plan
`python scripts/add_rule.py --name DoTheThing --prefix PL --code C0999
--linter pylint`
* Document codes.rs
* Refactor codes.rs before merging
Helper script:
```python
# %%
from pathlib import Path
codes = Path("crates/ruff/src/codes.rs").read_text().splitlines()
rules = Path("a.txt").read_text().strip().splitlines()
rule_map = {i.split("::")[-1]: i for i in rules}
# %%
codes_new = []
for line in codes:
if ", Rule::" in line:
left, right = line.split(", Rule::")
right = right[:-2]
line = left + ", " + rule_map[right] + "),"
codes_new.append(line)
# %%
Path("crates/ruff/src/codes.rs").write_text("\n".join(codes_new))
```

## Summary
This PR moves `Diagnostic`, `DiagnosticKind`, and `Fix` into their own crate, which will enable us to further split up Ruff, since sub-linter crates (which need to implement functions that return `Diagnostic`) can now depend on `ruff_diagnostics` rather than Ruff.
Currently the define_rule_mapping! macro generates both the Rule enum as
well as the RuleCodePrefix enum and the mapping between the two. After
this commit series the macro will only generate the Rule enum and the
RuleCodePrefix enum and the mapping will be generated by a new map_codes
proc macro, so we rename the macro now to fit its new purpose.

no-assert-raises-exception
Code: B017 (flake8-bugbear)
### What it does
Checks for `self.assertRaises(Exception)`.
## Why is this bad?
`assertRaises(Exception)` can lead to your test passing even if the
code being tested is never executed due to a typo.
Either assert for a more specific exception (builtin or custom), use
`assertRaisesRegex` or the context manager form of `assertRaises`.
```
- optional `prefix` argument for `add_plugin.py`
- rules directory instead of `rules.rs`
- pathlib syntax
- fix test case where code was added instead of name
Example:
```
python scripts/add_plugin.py --url https://pypi.org/project/example/1.0.0/ example --prefix EXA
python scripts/add_rule.py --name SecondRule --code EXA002 --linter example
python scripts/add_rule.py --name FirstRule --code EXA001 --linter example
python scripts/add_rule.py --name ThirdRule --code EXA003 --linter example
```
Note that it breaks compatibility with 'old style' plugins (generation works fine, but namespaces need to be changed):
```
python scripts/add_rule.py --name DoTheThing --code PLC999 --linter pylint
```
"origin" was accurate since ruff rules are currently always modeled
after one origin (except the Ruff-specific rules).
Since we however want to introduce a many-to-many mapping between codes
and rules, the term "origin" no longer makes much sense. Rules usually
don't have multiple origins but one linter implements a rule first and
then others implement it later (often inspired from another linter).
But we don't actually care much about where a rule originates from when
mapping multiple rule codes to one rule implementation, so renaming
RuleOrigin to Linter is less confusing with the many-to-many system.
