ui: use TimeScaleState reducer to align time window across pages

[koorosh]

Before, there was globalTimeScale local setting that was used to track time window changes in different places (ie statements, transactions and metrics pages). But Metrics page has many components that still rely on logic implemented in TimeScaleState reducer and MetricsTimeManager component that manages how to update moving time window in Db Console. As result, two places exist that track time window changes and they are not synced. It caused issues related to selecting custom time ranges on Metrics page.

This change does following:

• remove globalTimeScale local setting as a duplicate of TimeScaleState reducer.
• use TimeScaleState's logic to set and get current values of time window in SQL Activity pages.

Release note: None

On a video below you can see the result where changing time range in different places updates it across all pages. Also it shows that it works if user selects predefined relative time option or selects custom time range.

This PR undoes the proper object construction from local settings that existed in globalTimeScale.ts. This means if a user refreshes the page and we construct the timescale from session storage, certain properties of the timescale won't function properly, and the page will actually crash if fixedWindowEnd is non-null. I'll reintroduce this construction in another PR that should be backported.

FYI @xinhaoz this PR was followed by this other PR https://github.com/cockroachdb/cockroach/pull/86157 that did some fixes for the reload part
