This patch adds the most basic tab interaction metrics for tab groups.
As discussed in standup, we agreed to move the `remove_` class of
metrics into its own bug due to extra complexity involved in correctly
capturing these events.
One other thing we discussed was what the scope of events should be for
the `close_` class of events, i.e. should we *only* capture an event
when someone clicks the "X" button or closes from the TOM menu, or
should we also account for things like context menus, keyboard
shortcuts, etc.? Originally we agreed to capture _all_ tab close events
and mark any source that was not one of the above mentioned two as
unknown. However, after thinking about this more, I don't believe this
is the right approach. There are many places in the codebase where a tab
is closed but not because a user deliberately did it (e.g. when moving a
tab to a new window — this is actually done by creating a new tab in a
new window and closing the old). We currently don't distinguish between
user-initiated close actions, so it would take some time to find all
these places and exclude them.
I favour an explicit inclusion approach (which is what we are doing
elsewhere). In this patch I added events for:
- closing a tab from the "X" close button (`close_tabstrip`)
- closing a tab from the tab context menu (`close_tabstrip`)
- closing a tab from the TOM (`close_tabmenu`)
There are other places that could potentially be
addressed, so I suggest moving these to a follow-up bug and addressing
them for 139.

This patch exposes a groupId field on tabs.Tab objects in extensions.
On mobile (Android), the value is always -1.
On desktop, the value is the numeric representation composed from the
internal ID, which happens to fit in a safe integer. As long as the
browser is not running past year 2255, this works. As a fallback,
when an ID in a different format is encountered, the logic falls back
to returning a new unique ID based on a counter. This ID is then
stored in an internal in-memory map to maintain stable consistency.
Since it is unclear when exactly it is safe to discard this value, this
map is never cleared. This minor memory leak is acceptable because it
does not happen in practice, and even if it does, the number of tab
groups over the lifetime of a Firefox session is not going to reach
excessive values.

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.

Record when users delete an open group from the tab group context menu or delete an open group from a context menu in the all-tabs menu.
This will not record when users close a window or close all of the individual tabs in a tab group, even though those cases have the logical side effect of deleting a tab group.

Now that the ReviewChecker sidebar can auto-open and close, the logic for finding distinct navigations needs to be updated.
This allow us to detect the first time new products URLs are requested to shown in the sidebar and to check if a tab should auto-open the sidebar after it was closed.
- `isDistinctProductPageVisit` now works the same as it did in the ShoppingSidebar, indicating that there was a product navigation while a tab was in the background.
- `reviewCheckerWasClosed` now prevents the sidebar from re-opening on tab changes for a location it was closed on.
- `isSimulated` is set to false in the location change handlers on tab changes where there was an unhandled background product navigation.
- Moves the `isSameProduct` check to `ShoppingUtils` and use that to test previous URIs passed to `hasLocationChanged`.
- Manager will only handle product page specific parts of location changes when the sidebar is not open to handle them.

This is what UX has decided makes sense, and will be much less disruptive
than dimming out all favicons on session restore. When we're ready the
default value of "browser.tabs.fadeOutExplicitlyUnloadedTabs" will be
true, and the default value of "browser.tabs.fadeOutUnloadedTabs" will
remain false.
