As described on D111049, we're trying to remove the <string> dependency from error handling and replace uses of report_fatal_error(const std::string&) with the Twine() variant which can be forward declared.
Checks if introspection support is available set output kind parser.
If it isn't present the auto complete will not suggest `srcloc` and an error query will be reported if a user tries to access it.

LLVMTestingSupport is not part of libLLVM, and therefore can not
be linked to via LLVM_LINK_COMPONENTS. Instead, it needs to be
specified explicitly to ensure that it is linked explicitly

Currently errors detected when parsing the YAML for .clang-tidy files are always printed to errs.
For clang-tidy binary workflows this usually isn't an issue, but using clang-tidy as a library for integrations may want to handle displaying those errors in their own specific way.

Add methods for emitting diagnostics with no location as well as a special diagnostic for configuration errors.

The config providers that look for configuration files currently take a pointer to a FileSystem in the constructor.
For some reason this isn't actually used when trying to read those configuration files, Essentially it just follows the behaviour of the real filesystem.
Using clang-tidy standalone this doesn't cause any issue.
But if its used as a library and the user wishes to use say an `InMemoryFileSystem` it will try to read the files from the disc instead.

This cleans up several CMakeLists.txt's where -Wno-suggest-override was manually specified. These test targets now inherit this flag from the gtest target.
Some unittests CMakeLists.txt's, in particular Flang and LLDB, are not touched by this patch. Flang manually adds the gtest sources itself in some configurations, rather than linking to LLVM's gtest target, so this fix would be insufficient to cover those cases. Similarly, LLDB has subdirectories that manually add the gtest headers to their include path without linking to the gtest target, so those subdirectories still need -Wno-suggest-override to be manually specified to compile without warnings.

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.

add_compile_options is more sensitive to its location in the file than add_definitions--it only takes effect for sources that are added after it. This updated patch ensures that the add_compile_options is done before adding any source files that depend on it.
Using add_definitions caused the flag to be passed to rc.exe on Windows and thus broke Windows builds.
After lots of follow-up fixes, there are still problems, such as
-Wno-suggest-override getting passed to the Windows Resource Compiler
because it was added with add_definitions in the CMake file.
Rather than piling on another fix, let's revert so this can be re-landed
when there's a proper fix.

This patch adds `--use-color` command line option and `UseColor` option to clang-tidy to control colors in diagnostics. With these options, users can force colorful output.
