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.

Before commit b3a991df3c SystemHeaderMap used to be a vector.
Commit b3a991df3c changed it into a map, but neglected to remove
duplicate keys (e.g. "bits/typesizes.h", "include/stdint.h", etc.).
To prevent confusion, remove all duplicates, build HeaderMapping
one pair at a time and assert() that no duplicates are found.

where clangd's semantic highlighting is missing for symbols of a template
specialization definition. It turns out the visitor didn't traverse the
base classes of Class/Var##TemplateSpecializationDecl, i.e.
CXXRecordDecl/VarDecl. This patch adds them back as what is done in
DEF_TRAVERSE_TMPL_PART_SPEC_DECL.

When pretty printing the value of an expression, we cannot infer from
the type of the expression the type of the constant that the expression
evaluates to, as the expression might contain a type cast.
- Use the expression's type for non-C++ as the variable type. This works
well, but might not preserve the typedefs due to type
canonicalization.
- Improve support for Objective-C property references which are
represented using `ObjCPropertyRefExpr` and `BuiltinType::PseudoObject`.

Previously, clangd would filter completions only on the first part of
the selector (first typed chunk) instead of all remaining selector

Unfortunately I can't debug these at all - it's a bare unsymbolized
stacktrace, and I can't reproduce the failure.
This is a followup to D124715, which changed the default, and it anticipates
future patches raising the priority of Low (which is currently equal to
Background on Windows & Linux).
The main point is to allow users to restore the old behavior, which e.g.
allows efficiency cores to remain idle.
I did consider making this a config setting, this is a more complicated change:
- needs to touch queue priorities as well as thread priorities
- we don't know the priority until evaluating the config inside the task
- users would want the ability to prioritize background indexing tasks relative
to each other without necessarily affecting thread priority, so using one
option for both may be confusing
I don't really have a use case, so I prefer the simpler thing.

This provides a nice "warm start" with all headers indexed, not just
those included so far.
The standard library is indexed after a preamble is parsed, using that
file's configuration. The result is pushed into the dynamic index.
If we later see a higher language version, we reindex it.
It's configurable as Index.StandardLibrary, off by default for now.

Previously the Expr returned by getOperand() was actually the
subexpression common to the "ready", "suspend", and "resume"
expressions, which often isn't just the operand but e.g.
await_transform() called on the operand.
It's important for the AST to expose the operand as written
in the source for traversals and tools like clangd to work
correctly.

I am working on support for forwarding parameter names in make_unique-like functions, first for inlay hints, later maybe for signature help.
For that to work generically, I'd like to parse all of these functions in the preamble. Not sure how this impacts performance on large codebases though.

Disable the warnings with `IWYU pragma: export` or `begin_exports` +
`end_exports` until we have support for these pragmas. There are too many
false-positive warnings for the headers that have the correct pragmas for now
and it makes the user experience very unpleasant.

On Apple Silicon Macs, using a Darwin thread priority of PRIO_DARWIN_BG seems to
map directly to the QoS class Background. With this priority, the thread is
confined to efficiency cores only, which makes background indexing take forever.
Introduce a new ThreadPriority "Low" that sits in the middle between Background
and Default, and maps to QoS class "Utility" on Mac. Make this new priority the
default for indexing. This makes the thread run on all cores, but still lowers
priority enough to keep the machine responsive, and not interfere with
user-initiated actions.
I didn't change the implementations for Windows and Linux; on these systems,
both ThreadPriority::Background and ThreadPriority::Low map to the same thread
priority. This could be changed as a followup (e.g. by using SCHED_BATCH for Low
on Linux).
