There's many instances in clang tidy checks where owning strings are used when we already have a stable string from the options, so using a StringRef makes much more sense.

Adds a flag to `ClangTidyContext` that is used to indicate to checks that fixes will only be applied one at a time.
This is to indicate to checks that each fix emitted should not depend on any other fixes emitted across the translation unit.
I've currently implemented the `IncludeInserter`, `LoopConvertCheck` and `PreferMemberInitializerCheck` to use these support these modes.
Reasoning behind this is in use cases like `clangd` it's only possible to apply one fix at a time.
For include inserter checks, the include is only added once for the first diagnostic that requires it, this will result in subsequent fixes not having the included needed.
A similar issue is seen in the `PreferMemberInitializerCheck` where the `:` will only be added for the first member that needs fixing.
Fixes emitted in `StandaloneDiagsMode` will likely result in malformed code if they are applied all together, conversely fixes currently emitted may result in malformed code if they are applied one at a time.
For this reason invoking `clang-tidy` from the binary will always with `StandaloneDiagsMode` disabled, However using it as a library its possible to select the mode you wish to use, `clangd` always selects `StandaloneDiagsMode`.
This is an example of the current behaviour failing
```lang=c++
struct Foo {
int A, B;
Foo(int D, int E) {
A = D;
B = E; // Fix Here
}
};
```
Incorrectly transformed to:
```lang=c++
struct Foo {
int A, B;
Foo(int D, int E), B(E) {
A = D;
// Fix Here
}
};
```
In `StandaloneDiagsMode`, it gets transformed to:
```lang=c++
struct Foo {
int A, B;
Foo(int D, int E) : B(E) {
A = D;
// Fix Here
}
};
```

Change RewriteRule from holding an `Explanation` to being able to generate
arbitrary metadata. Where TransformerClangTidyCheck was interested in a string
description for the diagnostic, other tools may be interested in richer metadata
at a higher level of abstraction than at the edit level (which is currently
available as ASTEdit::Metadata).

This change applies two fixes to the abseil-cleanup-ctad check. It uses hasSingleDecl() to ensure only declStmt()s with one varDecl() are matched (leaving compount declStmt()s unchanged). It also addresses a bug in the handling of comments that surround the absl::MakeCleanup() calls by switching to the callArgs() combinator from Clang Transformer.

std::string, std::string_view, and absl::string_view all have a three-parameter version of find()
which has a "count" (or "n") paremeter limiting the size of the substring to search. We don't want
to propose changing to absl::StrContains in those cases. This change fixes that and adds unit tests
to confirm.

<string> is currently the highest impact header in a clang+llvm build:
https://commondatastorage.googleapis.com/chromium-browser-clang/llvm-include-analysis.html
One of the most common places this is being included is the APInt.h header, which needs it for an old toString() implementation that returns std::string - an inefficient method compared to the SmallString versions that it actually wraps.
This patch replaces these APInt/APSInt methods with a pair of llvm::toString() helpers inside StringExtras.h, adjusts users accordingly and removes the <string> from APInt.h - I was hoping that more of these users could be converted to use the SmallString methods, but it appears that most end up creating a std::string anyhow. I avoided trying to use the raw_ostream << operators as well as I didn't want to lose having the integer radix explicit in the code.

Differential Revision: https://reviews.llvm.org/D85843
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.

This additionally adds an explicit reference to FrontendOpenMP to
clang-tidy where ASTMatchers is used.
This is hopefully just a temporary solution. The dependence on
`FrontendOpenMP` from `ASTMatchers` should be handled by CMake
implicitly, not us explicitly.
