Save serializable options on the solution snapshot

This method tries to find the symbol that's defined by a particular
token, instead of a particular node. The approach was simply to bind
parent nodes until it found a symbol that had as the location the
original token. If it found a symbol that didn't match by location
it kept going up, so binding any identifier that doesn't define anything
would have always been fetching (and then throwing away) the symbols
for the containing members and type.

This tweaks it that once we find a symbol that doesn't match, we just
stop since we don't have a case where one symbol is contained in another
but the outer symbol is defined by some token inside the inner one.
There's definitely better ways to do this too but this is a fairly
straightforward improvement that doesn't require a fundamentally
different approach.

Fix race condition in CodeFixService

* Improve nullable analysis of local functions

This design tries to meld better analysis of nullable reference types in
local functions with performance. To keep the common case one pass,
local functions are analyzed using the starting state that is an
intersection of all the states before its usages (calls, delegate
conversions, etc), but the results of variables made nullable or
non-nullable inside the local function do not propagate to the callers.
