[Drilldowns] {{event.points}} in URL drilldown for VALUE_CLICK_TRIGGER

[Dosant]

Summary

We are not sure yet if we want this change

In case there is multiple points in context of VALUE_CLICK_TRIGGER (e.g. heat map cell clicked) currently URL Drilldown is showing a popup asking user to pick a value to drilldown to.

This pr extends event variables from VALUE_CLICK_TRIGGER to support multiple points:

Before:

When attaching a click to a heat map cell user don't have control over array of points:

{
key: string,
value: string,
negate: boolean
}

After:

URL template can use all the points:

{
key: string,
value: string,
negate: boolean
points: Array<{key: string, value: string}>
}

---

This change gives more flexibility and control to a user, but it also extends api surface.
This is a quick way to solve this corner case, that would work. But we are not sure if we want go with this.
This corner case and other corner cases described in details in this issue: #76226
