Emilia Dreamer 247613548b [clang-format] Change heuristic for locating lambda template arguments
Previously, the heuristic was simply to look for template argument-
specific keywords, such as typename, class, template and auto
that are preceded by a left angle bracket <.

This changes the heuristic to instead look for a left angle bracket <
preceded by a right square bracket ], since according to the C++
grammar, the template arguments must *directly* follow the introducer.
(This sort of check might just end up being *too* aggressive)

This patch also adds a bunch more token annotator tests for lambdas,
specifically for some of the stranger forms of lambdas now allowed as
of C++20 or soon-to-be-allowed as part of C++23.

Fixes https://github.com/llvm/llvm-project/issues/57093

This does NOT resolve the FIXME regarding explicit template lists, but
perhaps it gets closer

Emilia Dreamer bd3dd10a8b [clang-format] Concepts: allow identifiers after negation

Emilia Dreamer c6e7752f8e [clang-format] Allow `throw` to be a keyword in front of casts
This makes throw more similar to return. However, unlike return,
it has to more strict as to not remove spaces after usages of throw as

Emilia Dreamer f54d42abcf [clang-format] Don't put `noexcept` on empty line following constructor
With the AlwaysBreakTemplateDeclarations option, having a constructor
template for a type consisting of all-uppercase letters with a
noexcept specifier would put said noexcept specifier on its own blank
line.

This is because the all-uppercase type is understood as a macro-like
attribute (such as DEPRECATED()), and noexcept is seen as the
declaration. However, noexcept is a keyword and cannot be an
identifier on its own.

Gregory Fong e57f57841f [clang-format] fix alignment w/o binpacked args
The combination of

- AlignConsecutiveAssignments.Enabled = true
- BinPackArguments = false

would result in the first continuation line of a braced-init-list being
improperly indented (missing a shift) when in a continued function call.

direct-list-initialization.  Check for opening braced lists in
continuation and ensure that the correct shift occurs.

Marek Kurdej e20bc892b6 [clang-format] Fix PointerAlignment: Right not working with tab indentation.
Fixes https://github.com/llvm/llvm-project/issues/55407.

Given configuration:
```
UseTab: Always
PointerAlignment: Right
AlignConsecutiveDeclarations: true

Before, the pointer was misaligned in this code:
```
void f() {
	unsigned long long big;
	char	      *ptr; // misaligned
	int		   i;
}
```

That was due to the fact that when handling right-aligned pointers, the Spaces were changed but StartOfTokenColumn was not.

Also, a tab was used not only for indentation but for spacing too when using `UseTab: ForIndentation` config option:
```
void f() {
	unsigned long long big;
	char	      *ptr; // \t after char
	int                i;
