Remove old tooltips and annotations

[leeoniya]

before we can remove old tooltips, we need to deploy newVizTooltips in HG, and validate parity with old tooltips.

this is a sub-epic of #68238

we have started rollout of this feature toggle internally to dev and staging for dogfooding and feedback: https://github.com/grafana/deployment_tools/pull/124451

DRY

• Extract EventBus publisher and subscriber to plugin instead of duplicating code in each panel's prepConfig()
  • Verify bi-directional cursor/hover sync between Table and uPlot-based panels: Table: Highlight row on shared crosshair #78392
• Rework Heatmap tooltip code to share dataLink logic with other tooltips: Heatmap: Add datalink support #71016
• Unify and move cursor sync setup into TooltipPlugin2 from various prepConfig(): VizTooltips: Remove old tooltips and annotations #84420

Verify datalinks work correctly in all panels

• StatusHistory, StateTimeline
  • Re-check Status history/State timeline: Support datalinks #50226, https://github.com/grafana/support-escalations/issues/932
• TimeSeries
• Candlestick
• Trend
• BarChart
• XYChart
• Heatmap? (only non-numeric heatmap-rows case?)

Verify exemplars tooltip works correctly

• TimeSeries
• Heatmap

Verify other plugins play nice

• KeyboardPlugin (all x=time)
  • TimeSeries
  • StateTimeline
  • StatusHistory
  • Candlestick
  • Heatmap
• OutsideRangePlugin (all x=time)
  • Fix to check null in values, not in timestamps since OutsideRangePlugin: Exclude leading and trailing null values when checking limits #57335
  • TimeSeries
  • StateTimeline
  • StatusHistory
  • Candlestick
  • Heatmap
• ThresholdControlsPlugin
  • TimeSeries
• ExemplarsPlugin
  • TimeSeries

Remove old tooltip code from panels

• StateTimeline
• StatusHistory
• BarChart
• Trend
• Candlestick
• TimeSeries
• Heatmap
• XYChart

Remove now-unused components and features
