Sam McCall ad97ccf6b2 [clangd] Move non-clang base pieces into separate support/ lib. NFCI
Summary:
This enforces layering, reduces a sprawling clangd/ directory, and makes life
easier for embedders.

Sam McCall 915f9785e0 [clangd] Rename ClangdUnit.h -> ParsedAST.h. NFC
This much better reflects what is (now) in this header.
Maybe a rename to ParsedTU would be an improvement, but that's a much
more invasive change and life is too short.

ClangdUnit is dead, long live ClangdUnitTests!

This reverts commit 9c377105da.

[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.

Sam McCall 2f760c44e6 [clangd] Rewrite of logic to rebuild the background index serving structures.
Summary:
Previously it was rebuilding every 5s by default, which was much too frequent
in the long run - the goal was to provide an early build. There were also some
bugs. There were also some bugs, and a dedicated thread was used in production
but not tested.

 - rebuilds are triggered by #TUs built, rather than time. This should scale
   more sensibly to fast vs slow machines.
 - there are two separate indexed-TU thresholds to trigger index build: 5 TUs
   for the first build, 100 for subsequent rebuilds.
 - rebuild is always done on the regular indexing threads, and is affected by
   blockUntilIdle. This means unit/lit tests run the production configuration.
 - fixed a bug where we'd rebuild after attempting to load shards, even if there
   were no shards.
 - the BackgroundIndexTests don't really test the subtleties of the rebuild
   policy (for determinism, we call blockUntilIdle, so rebuild-on-idle is enough
   to pass the tests). Instead, we expose the rebuilder as a separate class and
   have fine-grained tests for it.
