This is primarily motivated by the desire to move from Python2 to
Python3. `PYTHON_EXECUTABLE` is ambiguous. This explicitly identifies
the python interpreter in use. Since the LLVM build seems to be able to
completed successfully with python3, use that across the build. The old
path aliases `PYTHON_EXECUTABLE` to be treated as Python3.
Summary:
Before this PR, `modernize-use-using` would transform the typedef in
```
template <int A>
struct InjectedClassName {
typedef InjectedClassName b;
};
```
into `using b = InjectedClassName<A>;` and
```
template <int>
struct InjectedClassNameWithUnnamedArgument {
typedef InjectedClassNameWithUnnamedArgument b;
};
```
into `using b = InjectedClassNameWithUnnamedArgument<>;`.
The first fixit is surprising because its different than the code
before, but the second fixit doesn't even compile.
This PR adds an option to the TypePrinter to print InjectedClassNameType without
template parameters (i.e. as written).

Summary:
This is on by default in windows and breaks most features in template bodies.
We'd already disabled it in code completion, now disable it for building ASTs.
Potential regressions:
- we may give spurious errors where files with templates relying on delayed
parsing are directly opened
- we may misparse such template bodies that are instantiated (and therefore
*were* previously parsed)
Still *probably* a win overall. Avoiding the regressions entirely would be
substantial work and we don't have plans for it now.

Summary:
This matches the conventional location of cmake build directories.
It also allows creating a `build` symlink, which seems more flexible than the
compile_commands.json symlinks.

Summary:
This is intended as a companion to (and is inspired by) D72874 which attempts to
resolve these cases using the index.
The intent is we'd try this strategy after the AST-based approach but before the
index-based (I think local usages would be more reliable than index matches).

Moving this out of the monorepo for consistency with other editor plugins.
There's no version lock with clangd itself, and we never ran tests with lit.
The first version from the new repo has been published.

Summary:
This is achieved by calculating newly added includes and implicitly
parsing them as if they were part of the main file.
This also gets rid of the need for consistent preamble reads.

Summary:
This is guaranteed to be a no-op without the preamble, so should be a
no-op with it too.
Partially fixes https://github.com/clangd/clangd/issues/337
This doesn't yet work for #ifndef guards, which are not recognized in preambles.
see D78038
I can't for the life of me work out how to test this outside clangd.
The original reentrant preamble diagnostic was untested, I added a test
to clangd for that too.

Summary:
Before this PR, `modernize-use-using` would transform the typedef in
```
template <typename a> class TemplateKeyword {
typedef typename a::template f<> e;
typedef typename a::template f<>::d e2;
};
```
into
```
template <typename a> class TemplateKeyword {
using d = typename a::b<>;
using d2 = typename a::template a::b<>::c;
};
```
The first one is missing the `template` keyword,
the second one has an extra `a::` scope. Both result
in compilation errors.

PreprocessorTracker is the last user of the old StringPool class, which
isn't super loved and isn't a great improvement over a plan StringSet.
Once this goes in we can remove StringPool entirely.

Summary:
This patch allows using installed gRPC to build two simple tools which
currently provide the functionality of looking up the symbol by name.
remote-index-client is a simplified version of dexp which connects to
remote-index-server passes lookup requests.
I also significantly reduced the scope of this patch to prevent large changelist
and more bugs. The next steps would be:
* Extending Protocol for deep copies of Symbol and inherit RemoteIndex from
Index to unify the interfaces
* Make remote-index-server more generic and merge the remote index client with
dexp
* Modify Clangd to allow using remote index instead of the local one for all
global index requests

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:
We want to be sure they don't cause AST rebuilds or evict items from the cache.
D77847 is going to start sending spurious no-op changes (in case the preamble
was invalidated), this is cheap enough but we shouldn't regress that in future.
