Brian Wilkerson 8c07071afb Use context type in the static member contributor
I couldn't think of any other features related to static members. Please
let me know if you can think of any.

I need to modify the metrics utility to be able to differentiate between
static and instance member references in order to measure the impact of
this approach. I'll look into doing that today. I suspect that we'll
eventually need it to split out results in many more ways as well.

Also updated some comments in an attempt to make it easier in the future
to determine which contributor to look at for bug fixes or enhancements.

Brian Wilkerson 90e32fe161 Disable other sorting when using the new relevance computation
This actually makes the scores slightly worse, but I think it's important
that we understand the quality of the scores without other sorting. The
scores are still better than with the old computation.

Mike Fairhurst 546acb1e8e [nnbd_migration] Split apart running tasks from sending dartfix response
This enables us to get code that we can execute to rerun dartfix in
later CLs.

One note is that this won't pick up on certain file changes, etc. I
think a better long-term solution is to rerun the entire DartFix code on
rerun, and that dartfix response can be returned directly to the js
front end. Its possible that the types of file changes this will miss
are extremely rare, such as changed .packages files only etc.

This would require a bit more untangling, things like managing the way that
dartfix will start a server each time, and ensuring that we get a
DartFix respnse *and* a migration state, so this CL seems worth landing
in the meantime. Filed as #41017

Brian Wilkerson b31445c0f8 Improve the relevance scores for instance type members
The "super matches" feature should have been disabled (-1.0) when the
target wasn't `super`, but it wasn't. That artificially lowered the
score for methods. But it wasn't being used (even when it should have
been) for getters and setters, so their scores weren't being lowered.
That accounted for the poor mrr I was seeing. This fixes both problems
so that the feature is now used everywhere when it should be and not
when it shouldn't be.

Paul Berry 93448a47c6 Migration: change trace view to alternate between edges and nodes.
Previously, we only included edges in the trace view, which resulted
in a lot of missing information.  Generally the reasoning process
looks like "type at A is nullable because of an expression at B, which
propagates nullability from a type at C, which is nullable because of
an expression at D, etc."  This change makes the trace reflect that
reasoning process better.

Mike Fairhurst 123a1ea517 [nnbd_migration] Fix 'apply edit' links.
Previously we would do a POST, but not prevent the default action of
clicking on the link, which is to navigate the browser.

Also, the URLs we generate begin with 'http' and therefore the
absolutePath call is not needed, and in fact, breaks the URL.

Paul Berry a74253987b Migration: add trace functionality to the preview tool.
This establishes the base functionality.  A lot of follow-up work is
needed from here:

- Each trace should have an entry at the top of it pointing to the
  thing that was made nullable.

- The source code links in traces don't include lengths, so we can't
  highlight whole identifiers when the user clicks on a link.

- Description strings are currently generated by running toString() on
  the individual nullability nodes and edges, resulting in long-winded
  and useless descriptions.
