fragment-testing:1.2.x has a strict version dependency on
androidx.test.core 1.2.x, preventing upgrading to 1.3.x

Test: ./run_all_tests.sh

Test: ./gradlew lib:cC app:cC

Also removed unused NetworkState.

Additionally, add cachedIn() to prevent re-load on rotation.

This reverts commit 61d7b0c5

And the requisite Gradle 5.6.4

Test: ./run_all_tests.sh

Rely on the `buildToolsVersion` that is bundled with the version of Android Gradle Plugin.

Test: ./run_all_tests.sh

Test: ./run_all_tests.sh

Test: ./run_all_tests.sh

Test: ./run_all_tests.sh

Allow for incrementally updating the `compileSdkVersion` before upgrading the `targetSdkVersion`. In this case, they are both API 29 so this is a no-op.

Test: ./run_all_tests.sh

Test: ./run_all_tests.sh

AndroidX Transition 1.2.0 is required for apps that target API 29 or higher and AndroidX Transition 1.3.0 is needed to take full advantage of the changes in Fragment 1.2.0.

Test: ./run_all_tests.sh

- Activity 1.0.0 -> 1.1.0
- Fragment 1.2.0-rc05 -> 1.2.0
- Lifecycle 2.2.0-rc03 -> 2.2.0
- Navigation 2.2.0-rc04 -> 2.2.0

Test: ./run_all_tests.sh

Sort the dependencies alphabetically to make it more consistent when adding new dependencies.

Test: ./run_all_tests.sh

Make it more clear that each artifact group is independent from one another.

Test: ./run_all_tests.sh

Remove the overly broad "support" version and instead provide a separate, explicit version for each group of artifacts.
