Bug 1662769. Make PrintSettingsViewProxy.resolvePropertiesForPrinter use the saved printer info. r=mstriemer

Differential Revision: https://phabricator.services.mozilla.com/D89154

Summary of changes:
1. Adds an `entry` property to the searchMode object to tag how search mode was entered.
2. Introduces `urlbar.searchmode.*` scalars.  These scalars are suffixed with an entry point into search mode, for example `urlbar.searchmode.oneoff`, or `urlbar.searchmode.topsites_urlbar`. Those entry points tell us how search mode is entered most often. The keys for these scalars are strings describing what kind of search mode was entered. In most cases, this will be the name of a search engine, like "Google", or "DuckDuckGo". It may also be one of "history", "bookmarks", or "tabs". We only collect the names of engines that are bundled with Firefox. If the user enters search mode with an engine they installed themselves, we record "other" as the key.
3. Adds a urlbar-searchmode SAP to SEARCH_COUNTS.
4. Adds a browser.engagement.navigation.urlbar_searchmode probe.
5. Adds a urlbar_searchmode SAP to the navigation.search event.

Bug 1662632 - Fix `UnboundLocalError` due to undefined variable `have_clone` in `mach bootstrap` r=froydnj

This consolidates the `have_clone` logic in one place unconditionally. After bug 1647792 we're deprecating the use case where `bootstrap` is run without a clone, so that's not a problem.

In reality the whole `have_clone` thing isn't necessary any more (`have_clone` is always going to be `True` in practice), but I'll save that for a bigger refactoring.

As long as we're following the STL guidelines on how to do iterators, we
should be annotating things with the bits that the STL iterator support
wants to see.

Move the function taking care of closing the Browser Console to shared-head so
we can close it before closing the tabs opened during the test.

While attaching the worker, check that the Worker Debugger isn't closed, and
if it is, reject the promise. On the target list, catch rejection while attaching
and simply bail out so we don't call the rest of the code in onTargetAvailable.

Those guards are not enough to prevent any failure while attaching, so we're
wrapping calls to `attachAndInitThread`/`_onThreadInitialized` in try/catch
blocks to avoid test failures.

At the moment, we don't have any guards in the targetList to _not_ execute the
creation/destruction listeners once the toolbox gets destroyed.
We only have a stopListening function on the targetList that is called when we
close the toolbox, but we can't rely only on that since it's also called when
doing a target switch (and working around that is very racy).

One solution would be to follow the common pattern we have everywhere by having
a destroy method that we would check before trying to call the listeners callback.

This might help with intermittent test failures.

Bug 1661030 - Refactor SubDialog and TabDialogBox to support passing multiple window arguments. r=Gijs,preferences-reviewers

This also updates the behavior of the allowDuplicates check:
Instead of only checking if the top dialog is a duplicate, it will now check the whole stack and
skip the dialog open if a duplicate URL is found.
This fixes an issue where callers could alternate between dialogs to bypass the check.
