Fix #4348: Prepare for Beta MR1 by updating version codes & pulling in the latest pt-BR translations (#4565)

## Explanation
Fixes #4348

This PR performs the final preparation tasks necessary for the MR1 Beta release to be cut. Specifically:
- It updates the version codes & minor version.
- It pulls the latest pt-BR translations (for the ones that didn't make it in the automatic Thursday Translatewiki push).
- It addresses the final open comments from #4081 which included me needing to do the pt-BR translation for 2 strings related to profile names (I used Google Translate then made minor modifications).

There are no tests affected directly by these changes (though we could consider adding some in the future).

## For UI-specific PRs only
For the most part this PR is not UI-tied (though obviously the 1 English string change and all of the pt-BR string changes affect UIs). I'm deciding not to include screenshots for string-only changes since they aren't very interesting in this case (i.e. they don't seem like they would actually break the UI to warrant including screenshots).

Commits:

* Create dedicated alpha application component.

This simplifies application component management significantly and
allows individual build flavors to have their own unique module lists.

* Add beta & GA update notices.

This also introduces dedicated beta & GA build flavors which is a
necessary prerequisite.

It also introduces an extra beta, alpha, and dev mode labels for the splash
screen (the latter 2 were extra) with 2 second minimum wait timers for
beta and alpha to ensure they are seen. A 5-second safety timer was
added to ensure the splash screen can always be passed even if something
goes wrong at the domain level (since there are now quite a few moving
pieces to determine the user's current onboarding state).

* Add build tests for the new beta & GA flavors.

* Fix broken test per earlier changes.

* Fix general broken tests & builds.

Tests broken due to changes to the app startup experience haven't yet
been fixed.

* Lint fixes.

* First part of adding tests for GA notices.

There's a bunch left to do here, this is mainly needed so that I can
transfer changes to a different machine.

* Update TransformAndroidManifestTest.kt

Correct typos.

* Fix tests & static checks.

This also removes temporary debug code and TODOs, and finishes the tests
for SplashActivity.

* Post-merge fixes.

* Test fixes.

* Fix Gradle test.

* Add some string resource checks/tools.

Also, fixes major performance issue with all file-based CI checks.

* Ensure newline consistency in translated strings.

Also, fix reporting in new validation check script.

* Add tests & fix static checks.

* Update version codes & pt-BR strings.

The strings were manually pulled Translatewiki.

* Follow-up adjustments after self-review.

* Add latest translated pt-BR strings.

* Address comments from #4081.
