This patch prints information about built index size estimation to
verbose logs. This is useful for optimizing memory usage of DexIndex and
comparisons with MemIndex.

Summary:
It was previously only indexing the preamble decls. The new
implementation will index both the preamble and the main AST and
report both sets of symbols, preferring the ones from the main AST
whenever the symbol is present in both.
The symbols in the main AST slab always store all information
available in the preamble symbols, possibly adding more,
e.g. definition locations.

Summary:
This is the first step of implementing Xrefs in clangd:
- add index interfaces, and related data structures.

Summary:
This allows dynamic index to have consistent URI schemes with the
static index which can have customized URI schemes, which would make file
proximity scoring based on URIs easier.

Summary:
This is more efficient and avoids data races when reading files that
come from the preamble. The staleness can occur when reading a file
from disk that changed after the preamble was built. This can lead to
crashes, e.g. when parsing comments.
We do not to rely on symbols from the main file anyway, since any info
that those provide can always be taken from the AST.

Summary:
This patch adds index support for GoToDefinition -- when we don't get the
definition from local AST, we query our index (Static&Dynamic) index to
get it.
Since we currently collect top-level symbol in the index, it doesn't support all
cases (e.g. class members), we will extend the index to include more symbols in
the future.

Summary:
Potential use case: argument go-to-definition result with symbol
information (e.g. function definition in cc file) that might not be in the AST.

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)
