This reverts commit 9c377105da0be7c2c9a3c70035ce674c71b846af.
[clangd][BackgroundIndexLoader] Directly store DependentTU while loading shard
Summary:
We were deferring the population of DependentTU field in LoadedShard
until BackgroundIndexLoader was consumed. This actually triggers a use after
free since the shards FileToTU was pointing at could've been moved while
consuming the Loader.

r366458 is causing test failures. r366467 and r366468 had to be reverted as
they were casuing conflict while reverting r366458.
r366468 [clangd] Remove dead code from BackgroundIndex

Summary:
Changes persistance logic to store shards at the directory of closest
CDB. Previously we were storing all shards to directory of the CDB that
triggered indexing, it had its downsides.
For example, if you had two TUs coming from a different CDB but depending on the
same header foo.h, we will store the foo.h only for the first CDB, and it would
be missing for the second and we would never persist it since it was actually
present in the memory and persisted before.
This patch still stores only a single copy of a shard, but makes the directory a
function of the file name. So that the shard place will be unique even with
multiple CDBs accessing the file. This directory is determined as the first
directory containing a CDB in the file's parent directories, if no such
directory exists we make use of the home directory.

part of check-clang-tools.
Summary:
Motivation:
- this layout is a pain to work with
- without a common root, it's painful to express things like "disable clangd" (D61122)
- CMake/lit configs are a maintenance hazard, and the more the one-off hacks
for various tools are entangled, the more we see apathy and non-ownership.
This attempts to use the bare-minimum configuration needed (while still
supporting the difficult cases: windows, standalone clang build, dynamic libs).
In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in.
The logic in these files is now minimal.
(Much of clang-tools-extra's lit configs can probably be cleaned up by reusing
lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of
LDPATH mangling. I haven't attempted to fix any of those).
Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.
