There were some left-overs (or new things) from the previous patches.
This will get us down to 0 open findings except:
clang-tidy is complaining in some files about
`warning: #includes are not sorted properly [llvm-include-order]`
however, clang-format does revert these changes.
It looks like clang-tidy and clang-format disagree there.
Not sure how we can fix that...

This updates all the non-runtime project release notes to use the
version number from CMake instead of the hard-coded version numbers
in conf.py.
It also hides warnings about pre-releases when the git suffix
is dropped from the LLVM version in CMake.

Auto-generated patch based on clang-tidy readability-identifier-naming.
Only some manual cleanup for `extern "C"` declarations and a GTest change was required.
I'm not sure if this cleanup is actually very useful. It cleans up clang-tidy findings to the number of warnings from clang-tidy should be lower. Since it was easy to do and required only little cleanup I thought I'd upload it for discussion.
One pattern that keeps recurring: Test **matchers** are also supposed to start with a lowercase letter as per LLVM convention. However GTest naming convention for matchers start with upper case. I would propose to keep stay consistent with the GTest convention there. However that would imply a lot of `//NOLINT` throughout these files.
To re-product this patch run:
```
run-clang-tidy -checks="-*,readability-identifier-naming" -fix -format ./clang-tools-extra/clangd
```
To convert the macro names, I was using this script with some manual cleanup afterwards:

Display notes for a possible call chain if an unsafe function is found to be
called (maybe indirectly) from a signal handler.
The call chain displayed this way includes probably not the first calls of
the functions, but it is a valid possible (in non path-sensitive way) one.

Inside a switch the caseStmt() and defaultStmt() have a nested statement
associated with them. Similarly, labelStmt() has a nested statement.
These statements were being missed when looking for a compound-if of the
form "if (x) return true; return false;" when the if is nested under one
of these labelling constructs.
Enhance the matchers to look for these nested statements using some
private matcher hasSubstatement() traversal matcher on case, default
and label statements. Add the private matcher hasSubstatementSequence()
to match the compound "if (x) return true; return false;" pattern.
- Add unit tests for private matchers and corresponding test
infrastructure
- Add corresponding test file readability-simplify-bool-expr-case.cpp.
- Fix variable name copy/paste error in readability-simplify-bool-expr.cpp.
- Drop the asserts, which were used only for debugging matchers.
- Run clang-format on the whole check.
- Move local functions out of anonymous namespace and declare state, per
LLVM style guide
- Declare labels constexpr
- Declare visitor arguments as pointer to const
- Drop braces around simple control statements per LLVM style guide
- Prefer explicit arguments over default arguments to methods

This commit checks if a function is marked with the naked attribute
and, if it is, will silence the emission of any unused-parameter
warning.
Inside a naked function only the usage of basic ASM instructions is
expected. In this context the parameters can actually be used by
fetching them according to the underlying ABI. Since parameters might
be used through ASM instructions, the linter and the compiler will have
a hard time understanding if one of those is unused or not, therefore
no unused-parameter warning should ever be triggered whenever a
function is marked naked.
This results in excessive memory usage and eats a lot of screen estate.
Especially in the cases with lots of nested macro calls.
This patch tries to remedy it before the release cut by suppressing the
initializers. For better UX we should probably update the expression printer to
truncate those (behind some policy).

The check previously inspected only the immediate parent namespace.
`static` in a named namespace within an unnamed namespace is still

Underscore-uglified identifiers are used in standard library implementations to
guard against collisions with macros, and they hurt readability considerably.
(Consider `push_back(Tp_ &&__value)` vs `push_back(Tp value)`.
When we're describing an interface, the exact names of parameters are not
critical so we can drop these prefixes.
This patch adds a new PrintingPolicy flag that can applies this stripping
when recursively printing pieces of AST.
We set it in code completion/signature help, and in clangd's hover display.
All three features also do a bit of manual poking at names, so fix up those too.

Support for NOLINT(BEGIN/END) blocks (implemented in D108560) is
currently costly. This patch aims to improve the performance with the
following changes:
- The use of tokenized NOLINTs instead of a series of repetitive ad-hoc
string operations (`find()`, `split()`, `slice()`, regex matching etc).
- The caching of NOLINT(BEGIN/END) block locations. Determining these
locations each time a new diagnostic is raised is wasteful as it
requires reading and parsing the entire source file.
Move NOLINT-specific code from `ClangTidyDiagnosticConsumer` to new
purpose-built class `NoLintDirectiveHandler`.

This commit introduces a new check `readability-container-contains` which finds
usages of `container.count()` and `container.find() != container.end()` and
instead recommends the `container.contains()` method introduced in C++20.
For containers which permit multiple entries per key (`multimap`, `multiset`,
...), `contains` is more efficient than `count` because `count` has to do
unnecessary additional work.
While this this performance difference does not exist for containers with only
a single entry per key (`map`, `unordered_map`, ...), `contains` still conveys
the intent better.
