This helps improve the syntax highlighting for Objective-C code,
although it currently doesn't work well in VS Code with
methods/properties/ivars since we don't currently include the proper
decl context (e.g. class).

This is the first patch in an ongoing attempt of Include Cleaner: unused/missing
headere diagnostics, an IWYU-like functionality implementation for clangd. The
work is split into (mostly) distinct and parallelizable pieces:
- Finding all referenced locations (this patch).
- Finding all referenced locations of macros.
- Building IncludeGraph and marking headers as unused, used and directly used.
- Making use of the introduced library and add an option to use in clangd.
---
* Adding support for standard library headers (possibly through mapping
genfiles).

This happens in createInvocationWithCommandLine but only clangd currently passes
ShouldRecoverOnErorrs (sic).
One cause of this (with correct command) is several -arch arguments for mac

Xcode uses `#pragma mark -` to draw a divider in the outline view
and `#pragma mark Note` to add `Note` in the outline view. For more
information, see https://nshipster.com/pragma/.
Since the LSP spec doesn't contain dividers for the symbol outline,
instead we treat `#pragma mark -` as a group with children - the
decls that come after it, implicitly terminating when the symbol's
parent ends.
The following code:
```
@implementation MyClass
- (id)init {}
- (int)foo;
@end
```
Would give an outline like
```
MyClass
> Overrides
> init
> Public Accessors
> foo
```

These aren't terribly common, but we currently mishandle them badly.
Not only do we not recogize the attributes themselves, but we often end up
selecting some node other than the parent (because source ranges aren't accurate
in the presence of attributes).

This patch strips all the arch options in case of multiple ones. As it
results in multiple compiler jobs, which clangd cannot handle.
It doesn't pick any over the others as it is unclear which one the user wants
and defaulting to host architecture seems less surprising. Users also have the
ability to explicitly specify the architecture they want via clangd config
files.

It is not great to list diag ids by hand, but I don't see any other
solution unless diagnostics are annotated with these explicitly, which is a
bigger change in clang and I am not sure if would be worth it.
Diagnostics handled by this patch is by no means exhaustive, there might be
other checks that don't mention "unused"/"deprecated" in their names. But it
feels like this should be enough to catch common diagnostics and can be extended
over time.

This seems to be a more useful behavior for tools that use preambles.
I believe it doesn't affect real compiles: the PCH is only included once
when used, and recursive inclusion of the main-file *within* the PCH
isn't supported in any case.

This reduces the size of the dependency graph and makes incremental
development a little more pleasant (less rebuilding).
This introduces a bit of complexity/fragility as some tests verify
clang-tidy behavior. I attempted to isolate these and build/run as much
of the tests as possible in both configs to prevent rot.
Expectation is that (some) developers will use this locally, but
buildbots etc will keep testing clang-tidy.

For files directly under clangd/, -Iclang-tools-extra/clangd (and the
equivalent for generated files) are not required, as CMake/the compiler puts
these directories on the include path by default.
However this means each subdirectory needs to
include_directories(.. ${CMAKE_CURRENT_BINARY_DIR}/..) etc, and this
proved annoying and error-prone to maintain and debug.
Since include_directories is inherited by subdirectories, we just
configure this explicitly at the top level instead.
Objective-C lets you use the `self.prop` syntax as sugar for both
`[self prop]` and `[self setProp:]`, but clangd previously did not
provide a semantic token for `prop`.
Now, we provide a semantic token, treating it like a normal property
except it's backed by a `ObjCMethodDecl` instead of a
`ObjCPropertyDecl`.
