Set aria-setsize on grouped tabs to the number of tabs in the tab group. Set aria-posinset on grouped tabs to the 1-based index of the tab within the tab group. This allows some a11y tools to report to the user that a tab is, for example, tab "2 of 7" in a tab group.
The tab strip uses the `tablist` ARIA role. The ARIA spec and Firefox's a11y engine both forbid nesting `group` ARIA roles inside of `tablist`. As a result, a11y tools always read individual tabs as being tab "X of Y", where Y is the number of tabs in the tab strip and X is the index of the tab in the tab strip. This is good information, but it does not give the user a sense of where a tab is within a tab group.

Tabs outside of tab groups are at the top level (level 1) while tabs inside of tab groups are at the next lower level (level 2). This helps unsighted users get a better sense about the hierarchy of the tab strip.

When using the tab context menu or drag-dropping tabs to put them into a group, record a metric for the number of tabs added to the group.
Data Science asked us to launch with this metric disabled so that they could control it using server knobs. They expect a high volume of events, so they expect to only enable this metric for some proportion of users.
I converted the existing `TabMove` event derived from `UIEvent` being fired when tabs change their tab index in the tab strip. `UIEvent` doesn't allow for attaching additional context/detail to the event. `TabMove` is now a `CustomEvent` that provides more context about the moved tab and it fires in more cases -- it's possible for the tab index not to change despite the tab having "moved" into/out of a tab group.
This approach would not capture tab movements that occur across multiple frames/event loop iterations.

This patch adds a `closedGroups` array to the SessionRestore state, and
adds functionality that ensures closed tab groups end up in the closed
groups array and that closed tab counts respect closed groups.
This does not update `undoClosedTab` or any related methods. Attempting
to restore a closed tab group will result in an error.
