This is a renewed attempt to land @toddlipcon's D34654. The comments on
that patch indicate a broad desire for some ability to ignore headers.
After considering various options, including migrating to std::regex, I
believe this is the best path forward. It's intuitive to have separate
regexes for including headers versus excluding them, and this approach
has the added benefit of being completely opt-in. No existing configs
will break, regardless of existing HeaderFilterRegex values.
This functionality is useful for improving performance when analyzing a
targeted subset of code, as well as in cases where some collection of
headers cannot be modified (third party source, for example).
Some options take the maximum unsigned integer value as default, but
they are being dumped to a string as integers. This makes -dump-config
write invalid '-1' values for these options. This change fixes this
issue by using utostr if the option is unsigned.
Fixes#60217
If a parameter value is either 'none', 'null', 'false', '-1'
or '', we will in that case use the default value.

The current way to specify CheckOptions is pretty verbose and unintuitive.
Given that the options are a dictionary it makes much more sense to treat them as such in the config files.
Example:
```
CheckOptions: {SomeCheck.Option: true, SomeCheck.OtherOption: 'ignore'}
# Or
CheckOptions:
SomeCheck.Option: true
SomeCheck.OtherOption: 'ignore'
```
This change will still handle the old syntax with no issue, ensuring we don't screw up users current config files.
The only observable differences are support for the new syntax and `-dump=config` will emit using the new syntax.

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

Following on fcf7cc268fe and 672207c319a 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`.
This is in line with how clang-format dumps boolean options in its style config.

Extend the `InheritParentConfig` support introduced in D75184 for the command line option `--config`.
The current behaviour of `--config` is to when set, disable looking for `.clang-tidy` configuration files.
This new behaviour lets you set `InheritParentConfig` to true in the command line to then look for `.clang-tidy` configuration files to be merged with what's been specified on the command line.

Summary:
Without this patch clang-tidy stops finding file configs on the nearest
.clang-tidy file. In some cases it is not very convenient because it
results in common parts duplication into every child .clang-tidy file.
This diff adds optional config inheritance from the parent directories
config files.
Test Plan:
Added test cases in existing config test.

Summary:
This change moves tests for checkers and infrastructure into separate
directories, making it easier to find infrastructure tests. Tests for
checkers are already easy to find because they are named after the
checker. Tests for infrastructure were difficult to find because they
were outnumbered by tests for checkers. Now they are in a separate
directory.
