Before, the code:
```
int Value { get; } = 0;
int Value { init; } = 0;
```
was formatted incoherently:
```
int Value { get; } = 0;
int Value { init; }
= 0;
```
because `init` was not recognised as an accessor specifier.

When handling `AllowShortFunctionsOnASingleLine`, we were searching for the last line with a smaller level than the current line. The search was incorrect when the first line had the same level as the current one. This led to an unsatisfied assumption about the existence of a brace (non-comment token).

We have a little problem. TokenAnnotator::resetTokenMetadata() resets
the type, except for a (growing) whitelist. This is because the
TokenAnnotator visits some tokens multiple times. E.g. trying to
identify if a < is an operator less or a template opener. And in some
runs, which are bascially "reverted" the types are reset.
On the other hand, if the parser does already know the type, it should
be able to set it, without it being reset. So we introduce the ability
to set a type and make that final.

This is a solution for standard C++ casts: const_cast, dynamic_cast, reinterpret_cast, static_cast.
A general approach handling all possible casts is not possible without semantic information.
Consider the code:
```
static_cast<T>(*function_pointer_variable)(arguments);
```
vs.
```
some_return_type<T> (*function_pointer_variable)(parameters);
// Later used as:
function_pointer_variable = &some_function;
return function_pointer_variable(args);
```
In the latter case, it's not a cast but a variable declaration of a pointer to function.
Without knowing what `some_return_type<T>` is (and clang-format does not know it), it's hard to distinguish between the two cases. Theoretically, one could check whether "parameters" are types (not a cast) and "arguments" are value/expressions (a cast), but that might be inefficient (needs lots of lookahead).

Given the config:
```
BasedOnStyle: LLVM
QualifierAlignment: Custom
QualifierOrder: ['constexpr', 'type']
```
The code:
```
template <typename F>
requires std::invocable<F>
constexpr constructor();
```
was incorrectly formatted to:
```
template <typename F>
requires
constexpr std::invocable<F> constructor();
```
because we considered `std::invocable<F> constexpr` as a type, not recognising the requires clause.
This patch avoids moving the qualifier across the boundary of the requires clause (checking `ClosesRequiresClause`).

In 529aa4b011
by setting the identifier info to nullptr, we started to subtly
interfere with the parts in the beginning of the function,
529aa4b011/clang/lib/Format/UnwrappedLineParser.cpp (L991)
causing the preprocessor nesting to change in some cases. E.g., for the
added regression test, clang-format started incorrectly guessing the

This tries to address this by introducing an internal identifier info

That's probably because of `)` being annotated as `CastRParen` instead of `Unknown` before, hence being kept on the same line with the next token.

Fixes https://github.com/llvm/llvm-project/issues/38160.
This patch splits `TT_RecordLBrace` for classes/enums/structs/unions (and other records, e.g. interfaces) and uses the brace type to avoid the error-prone scanning for record token.
The mentioned bugs were provoked by the scanning being too limited (and so not considering `const` or `constexpr`, or other qualifiers, on an anonymous struct variable declaration).
Moreover, the proposed solution is more efficient as we parse tokens once only (scanning being parsing too).
