Fix #1833: Rename package to org.oppia.android (part 2/2) (#1876)

* Move all source files to new org/oppia/android directory structure. No
actual package or code references are updated yet.

* Update Kotlin & XML references to match new package structure.

* Migrate codepaths for Bazel builds to new package structure.

* Fix package references in Gradle files for new package structure.

* Update package & pathing references to new structure for proto files.

* Rename Android package to org.oppia.android.

This includes introducing a new developer Firebase project. It also
fixes references to Android resource R file imports & databinding since
they both exist at the package level rather than the app module level.

* Fix Bazel builds for new package structure.

This required some changes to test setup/arrangement in Bazel, and some
existing issues needed to be fixed (missing dependencies for work
manager, switching multidex, one renamed test, incorrect module
references in tests, and files now referencing resources needing to be
moved).

This includes some Bazel file reformatting that happened automatically
by my Bazel file plugin.

* Resolve merge conflicts.

This won't compile due to duplicate imports which requires a ktlint
clean-up. That will happen in a subsequent commit since it will likely
pick up unrelated changes.

* Remove some merge conflict markers that were missed.

* Remove redundant commits & other ktlint updates.

* Fix incorrect references to new testing package location.

* Post-testing module cleanups via ktlint.

* More post-merge fixes.

Fix new references to R and databinding. Move EditTextInputAction to
correct package.

* Move some missed files that only caused breakages in Bazel.

* Move all files to their correct new location.

This moves all Kotlin source files to be under an org.oppia.android
structure, but does not actually change references. This is done in two
steps to try and preserve history, and to simplify the code review.

THIS WILL BREAK THE CODEBASE WHEN CHECKED IN.

* Fix missed files from the migration after merging.

* Disable Firebase data collection.

* Update BUILD.bazel
