The action='store_true' option of argparse.add_argument implicitly
generates a default value of False if the argument is not specified.
Thus, the allow_enabling_alpha_checkers argument of
get_tidy_invocation is never None.
The Abseil-NoInternalDependenciesCheck currently mistakenly triggers on any usage of internal helpers even if it is within absl/status.

Skeleton checks generated by clang-tidy add_check.py cause assertions to fail when run over anonymous functions(lambda functions). This patch introduces an additional check to verify that the target function is not anonymous before calling getName().

Currently, changes to includes are applied to an entire rule. However,
include changes may be specific to particular edits within a rule (for example,
they may apply to one file but not another). Also, include changes may need to
carry metadata, just like other changes. So, we make include changes first-class
edits.

Inside clangd, clang-tidy checks don't see preprocessor events in the preamble.
This leads to `Token::PtrData == nullptr` for tokens that the macro is defined to.
E.g. `#define SIGTERM 15`:
- Token::Kind == tok::numeric_constant (Token::isLiteral() == true)
- Token::UintData == 2
- Token::PtrData == nullptr
As the result of this, bugprone-bad-signal-to-kill-thread check crashes at null-dereference inside clangd.

When checking for the style of a decl that isn't in the main file, the check will now search for the configuration that the included files uses to gather the style for its decls.
This can be useful to silence warnings in header files that follow a different naming convention without using header-filter to silence all warnings(even from other checks) in the header file.

Ordering of options isn't important so an `llvm::StringMap` is a much better container for this purpose.

Handle insertion fix-its when removing incompatible errors by introducting a new EventType `ET_Insert`
This has lower prioirty than End events, but higher than begin.
Idea being If an insert is at the same place as a begin event, the insert should be processed first to reduce unnecessary conflicts.
Likewise if its at the same place as an end event, process the end event first for the same reason.
This also fixes https://bugs.llvm.org/show_bug.cgi?id=46511.

The previous fix for this, https://reviews.llvm.org/D76761, Passed test cases but failed in the real world as std::string has a non trivial destructor so creates a CXXBindTemporaryExpr.
This handles that shortfall and updates the test case std::basic_string implementation to use a non trivial destructor to reflect real world behaviour.

Simplified how `IncludeInserter` is used in Checks by abstracting away the SourceManager and PPCallbacks inside the method `registerPreprocessor`.
Changed checks that use `IncludeInserter` to no longer use a `std::unique_ptr`, instead the IncludeInserter is just a member of the class thats initialized with an `IncludeStyle`.
Saving an unnecessary allocation.
This results in the removal of the field `IncludeSorter::IncludeStyle` from the checks, as its wrapped in the `IncludeInserter`.
No longer need to create an instance of the `IncludeInserter` in the registerPPCallbacks, now that method only needs to contain:
```
Inserter.registerPreprocessor(PP);
```
Also added a helper method to `IncludeInserter` called `createMainFileInclusionInsertion`, purely sugar but does better express intentions.

Following on fcf7cc268f and 672207c319 which granted checks the ability to read boolean configuration arguments as `true` or `false`.
This enables storing the options back to the configuration file using `true` and `false`.

Summary:
This feature was only used in two places, but contributed a non-trivial
amount to the complexity of RecursiveASTVisitor, and was buggy (see my
recent patches where I was fixing the bugs that I noticed). I don't
think the convenience benefit of this feature is worth the complexity.
Besides complexity, another issue with the current state of
RecursiveASTVisitor is the non-uniformity in how it handles different
AST nodes. All AST nodes follow a regular pattern, but operators are
special -- and this special behavior not documented. Correct usage of
RecursiveASTVisitor relies on shadowing member functions with specific
names and signatures. Near misses don't cause any compile-time errors,
incorrectly named or typed methods are just silently ignored. Therefore,
predictability of RecursiveASTVisitor API is quite important.
This change reduces the size of the `clang` binary by 38 KB (0.2%) in
release mode, and by 7 MB (0.3%) in debug mode. The `clang-tidy` binary
is reduced by 205 KB (0.3%) in release mode, and by 5 MB (0.4%) in debug
mode. I don't think these code size improvements are significant enough
to justify this change on its own (for me, the primary motivation is
reducing code complexity), but they I think are a nice side-effect.
