compilationDatabaseChanges in the 'workspace/didChangeConfiguration' request
This commit allows clangd to use an in-memory compilation database that's
controlled from the LSP client (-compile_args_from=lsp). It extends the
'workspace/didChangeConfiguration' request to allow the client to pass in a
compilation database subset that needs to be updated in the workspace.

Summary:
log() is split into four functions:
- elog()/log()/vlog() have different severity levels, allowing filtering
- dlog() is a lazy macro which uses LLVM_DEBUG - it logs to the logger, but
conditionally based on -debug-only flag and is omitted in release builds
All logging functions use formatv-style format strings now, e.g:
log("Could not resolve URI {0}: {1}", URI, Result.takeError());
Existing log sites have been split between elog/log/vlog by best guess.
This includes a workaround for passing Error to formatv that can be
simplified when D49170 or similar lands.

Summary:
Caching is now handled by ClangdLSPServer and hidden behind the
GlobalCompilationDatabase interface. This simplifies ClangdServer.
This change also removes the SkipCache flag from addDocument,
which is now obsolete.
No behavioral changes are intended, the clangd binary still caches the
compile commands on the first read.

Summary:
Implementation of DidChangeConfiguration notification handling in
clangd. This currently only supports changing one setting: the path of
the compilation database to be used for the current project. In other
words, it is no longer necessary to restart clangd with a different
command line argument in order to change the compilation database.

Summary:
Instead of passing Context explicitly around, we now have a thread-local
Context object `Context::current()` which is an implicit argument to
every function.
Most manipulation of this should use the WithContextValue helper, which
augments the current Context to add a single KV pair, and restores the
old context on destruction.
Advantages are:
- less boilerplate in functions that just propagate contexts
- reading most code doesn't require understanding context at all, and
using context as values in fewer places still
- fewer options to pass the "wrong" context when it changes within a
scope (e.g. when using Span)
- contexts pass through interfaces we can't modify, such as VFS
- propagating contexts across threads was slightly tricky (e.g.
copy vs move, no move-init in lambdas), and is now encapsulated in
the threadpool
Disadvantages are all the usual TLS stuff - hidden magic, and
potential for higher memory usage on threads that don't use the
context. (In practice, it's just one pointer)

Summary:
- GlobalCompilationDatabase now returns a single command (that's all we use)
- fallback flags are now part of the GlobalCompilationDatabase.
There's a default implementation that they can optionally customize.
- this allows us to avoid invoking the fallback logic on two separate codepaths
- race on extra flags fixed by locking the mutex
- made GCD const-correct (DBGCD does have mutating methods)

Summary:
This patch adds the ability to specify user-defined extra flags per opened file
through the LSP layer. This is a non-standard extension to the protocol.
I've already created a feature request about it for upstream lsp:
https://github.com/Microsoft/language-server-protocol/issues/255
The particular use-case is ycmd, which has a python script for figuring out
extra flags per file:

Summary:
This commit restores r303067(reverted by r303094) and fixes the 'formatting.test'
failure.
The failure is due to destructors of `ClangdLSPServer`'s fields(`FixItsMap` and
`FixItsMutex`) being called before destructor of `Server`. It led to the worker
thread calling `consumeDiagnostics` after `FixItsMutex` and `FixItsMap`
destructors were called.
Also, clangd is now run with '-run-synchronously' flag in 'formatting.test'.
