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: Implemention of textDocument/hover as described in LSP definition.
This patch adds a basic Hover implementation. When hovering a variable,
function, method or namespace, clangd will return a text containing the
declaration's scope, as well as the declaration of the hovered entity.
For example, for a variable:
Declared in class Foo::Bar
int hello = 2
For macros, the macro definition is returned.
This patch doesn't include:
- markdown support (the client I use doesn't support it yet)
- range support (optional in the Hover response)
- comments associated to variables/functions/classes
They are kept as future work to keep this patch simpler.
I added tests in XRefsTests.cpp. hover.test contains one simple
smoketest to make sure the feature works from a black box perspective.

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)

Going to add unit tests in the next patch. (Haha!) But seriously there's
some work to do first - need to extract the markers-in-source-code
parser from CodeComplete test and make it more flexible, to allow
annotated ranges etc.
