fix(explore): Improve chart empty-state guard

[sentry]

TimeSeriesWidgetVisualization expects that the data it gets can be plotted. Caller components should guard against this case, and put up an appropriate empty state, probably TimeSeriesWidgetVisualization.NoData. Explore wasn't guarding this state, so it relies on the default handling, which shows a vague error screen, and barfs up an error into Sentry. This PR adds the correct guard, which adds the proper empty state.

Closes JAVASCRIPT-34B7

@sentry I just merged #119940 to master which creates a new pattern for this state, can you update this PR to use the code from that branch?

This PR is mergeable. Seer unfortunately did not have context of other work-in progress so it made a change at the same time as another PR I'm working on in the same area.

This is a good problem type for Seer, and Seer did appropriately diagnose this and choose a correct solution. It stumbled while iterating on this, and had to be guided.

The PR description, as usual, is pretty bad. 500 words where 100 would do.
