This change adds documentation to the completion items. This normally
should be done in completionItem/resolve, since it takes more time to
compute documentation. However, I am not sure if that latency incurred
by pre-computing documentation is actually significantly more than the
latency incurred by an extra call to 'completionItem/resolve'. This
needs to be investigated, so we begin by just precomputing all of the
documentation for each item.

We err on the side of refreshing package metadata if something goes
wrong getting a file's AST, but we don't want to refresh in the case
of context cancellation. Now we check for that error explicitly.
In particular, I noticed that completions would stop working when
typing quickly. Refreshing the metadata triggers "go list" calls which

The first deadlock involved differing mutex acquisition order in two
code paths:
1. loadParseTypecheck() holds the "mcache" mutex then eventually
acquires the "handleMu" file mutex.
2. (*goFile).invalidateContent() acquires the "handleMu" mutex first and
then the "mcache" mutex.
Fix by changing the acquisition order in invalidateContent().
The second deadlock involved the file watcher. The two code paths
involved were:
1. (*goFile).GetPackages() holds the view mutex and eventually calls
(*WatchMap).Watch, which acquires the watcher mutex.
2. (*session).openOverlay acquires the watcher mutex as it triggers a
file's callbacks, and then the callback
"(*goFile).invalidateContent" acquires the view mutex.
Fix by not holding the watcher mutex as we invoke the callbacks.

Add some extra smarts when evaluating untyped constants as completion
candidates. Previously we called types.Default() on the expected type
and candidate type, but this loses the untypedness of an untyped
constant which prevents it from being assignable to any type or named
type other than the untyped constant's default type.
Note that the added logic does not take into account the untyped
constant's value, so you will still get some false positive
completions (e.g. suggesting an untyped negative integer constant when
only a uint would do). Unfortunately go/types doesn't provide a way of
answering the question "is this *types.Const assignable to this
types.Type" since types.AssignableTo only considers a constant's type,
not its value.

Deep completion refers to searching through an object's fields and
methods for more completion candidates. For example:
func wantsInt(int) { }
var s struct { i int }
wantsInt(<>)
Will now give a candidate for "s.i" since its type matches the
expected type.
We limit to three deep completion results. In some cases there are
many useless deep completion matches. Showing too many options defeats
the purpose of "smart" completions. We also lower a completion item's
score according to its depth so that we favor shallower options. For
now we do not continue searching past function calls to limit our
search scope. In other words, we are not able to suggest results with
any chained fields/methods after the first method call.
Deep completions are behind the "useDeepCompletions" LSP config flag
for now.
