Muir Manders 4298585011 internal/lsp: provide deep completion candidates
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.
