[clang-format] Improve brace wrapping and add an option to control indentation of `export { ... }` (#110381)

`export { ... }` blocks can get a bit long, so I thought it would make
sense to have an option that makes it so their contents are not indented
(basically the same argument as for namespaces).

This is based on the `NamespaceIndentation` option, except that there is
no option to control the behaviour of `export` blocks when nested because
nesting them doesn’t really make sense.

Additionally, brace wrapping of short `export { ... }` blocks is now controlled by the
`AllowShortBlocksOnASingleLine` option. There is no separate option just for `export`
blocks because you can just write e.g. `export int x;` instead of `export { int x; }`.

This closes #121723.

[clang-format] Stop crashing on slightly off Verilog module headers (#116000)

This piece of code made the program crash.

```Verilog
function pkg::t get
(int t = 2,
int f = 2);
```

The way the code is supposed to be parsed is that UnwrappedLineParser
should identify the function header, and then TokenAnnotator should
recognize the result. But the code in UnwrappedLineParser would
mistakenly not recognize it due to the `::`. Then TokenAnnotator would
recognize the comma both as TT_VerilogInstancePortComma and
TT_VerilogTypeComma. The code for annotating the instance port comma
used `setFinalizedType`. The program would crash when it tried to set
it to another type.

The code in UnwrappedLineParser now recognizes the `::` token.

The are other cases in which TokenAnnotator would recognize the comma as
both of those types, for example if the `function` keyword is removed.
The type is now set using `setType` instead so that the program does not
crash. The developer no longer knows why he used `setFinalizedType`
back then.

[clang-format] Make bitwise and imply requires clause (#110942)

This patch adjusts the requires clause/expression parser to imply a
requires clause if it is preceded by a bitwise and operator `&`, and
assume it is a reference qualifier. The justification is that bitwise
operations should not be used for requires expressions.

This is a band-aid fix. The real problems lie in the lookahead heuristic
in the same method. It may be worth it to rewrite that whole heuristic
to track more state in the future, instead of just blindly marching
forward across multiple unrelated definitions, since right now, the
definition following the one with the requires clause can influence
whether the heuristic chooses clause or expression.

[clang-format] Introduce "ReflowComments: IndentOnly" to re-indent comments without breaking internal structure (think Doxygen). (#96804)

* Convert `ReflowComments` from boolean into a new `enum` which can take
on the value `RCS_Never`, `RCS_IndentOnly`, or `RCS_Always`. The first
one is equivalent to the old `false`, the third one is `true`, and the
middle one means that multiline comments should only have their
indentation corrected, which is what Doxygen users will want.
* Preserve backward compatibility while parsing `ReflowComments`.
