Disable zooming if Timeline Chart not based on timestamp field.

[dennisoelkers]

Description

Motivation and Context

This is a follow-up to #23909. When using alternative timestamp fields, we are disabling the zoom handler, as it changes the time range. This works reliably only if the chart is based on the timestamp field as well.

Fixes the described problem and zooming into the chart no longer changes the time range.

Some thoughts:

1. With this approach it is still possible to zoom into the chart, in 6.3 we disabled the zoom in this case completely. I like having the option to always zoom into a timeline chart, but it might be confusing for users, why it has different side effects, depending on the selected field.

2. When you increase the time range via the plotly controls (for a non timerange timeline), we do not fetch the related results, although there are some.

There seem to be some failing tests, but the recent changes work well.
