Bug 41684: Android improvements for local dev builds

Added a script to fetch the Tor dependencies from tor-browser-build,
and print the name of the signed apk.

The new version will contain the support for allowing to style download dialogs.

This uses the same direction as the before patch - inflating a new View that
can then serve as an anchor for the Snackbar.
Here we could use directly the AC layout as it needed no special customization.

Tried to mimic the UX of a modal dialog while using Android Views.
This meant including a scrim that would consume all touches and theming the
navigation bar and status bar.
Avoiding a dialog and a separate window will allow the snackbar to see the
new "dialog" as a sibling in a CoordinatorLayout parent and so be able to
position itself based on the new "dialog".
This patch also added "start_download_dialog_layout" from A-C as it leads to
simpler and less code needed to style the layout - colors / shapes with
everything happening in XML versus calculating the values then setting them
programatically.

Previously Android-Components - BrowserToolbarBehavior would be responsible
for positioning the snackbar above the toolbar.
With that responsibility removed we can handle in Fenix positioning the
snackbar depending on the toolbar and many more cases - like positioning it
depending on the download dialogs.

Also, we hide the uninstall button for builtin addons.

Bug 40059: Use MOZ_BUILD_DATE for versionCode

At the same time we adapt MOZ_BUILD_DATE to our needs where it is
actually used and not in tor-browser-build. This gives us more
flexibility. See: tor-browser-build#40084.

Bug 40067: Fix reproducibility issue in classes2.dex

We make sure our MOZ_BUILD_DATE gets used as a source for showing date
related information on the Fenix about page.

Bug 40123: Allow building the instrumented tests apks for variants other than debug

This allows to specify the variant of the instrumented tests via
a `testBuildType` gradle argument. It also applies a workaround for
a R8 issue from https://issuetracker.google.com/issues/140851070.

Bug 40143: Use deterministic date in Test apk

The build config was using Date() when generating the Test apk's
versionName.
