fix(tracemetrics): Resolve all equations at once when subcomponents update

[narsaynorath]

Pretend you have equations A + 1, and 1 / A, the previous code was only updating 1 / A in response to A changing because each equation (i.e. ƒ1, ƒ2) was triggering its own navigate which would clobber previous updates, so ƒ1 would fire and cue up a navigate to update the equation, then ƒ2 would fire and cue up its own navigate, and when they were processed, only ƒ2 was shown to be updated (since the URL is parsed to determine the metric queries and the URL now only contained new ƒ2 state)

This PR adds in a sync functionality that batches up all of the metric query changes and dispatches a single navigate call. I had to extract some methods out into helpers to do this, which explains some of the larger diff. equationBuilder.tsx was essentially renamed and nested under a folder so I could colocate utils from the old file.

It removes the reference syncing responsibility from the equation builder and pushes it to the points where updates to metric queries happens. The effect of this is that we can update things in one go instead of as a side effect of something else changing.
