Fixed bug where opening a window while splash is in mid-transition causes splash to adopt child window's transition. Causes noticeable stutter.
  * Especially an issue as of Android Q beta 4.
  * Modified so that activity windows launched from splash override pending transition with fade-in transition instead. (Looks better than slide-up animation anyways.)

Fixes TIMOB-27328

- Fixed so that Android setting <uses-feature/> required "true" in "tiapp.xml" should override "false" setting in libraries.
  * Merge is supposed to do a logical-OR on the "android:required" value.
- Added "tools:replace" attribute support to <uses-feature/>.
  * Allows overriding "android:required" to "false" if set "true" by library. (Only means of doing this.)

Fixes TIMOB-27304

Fixes TIMOB-27266

* [TIMOB-27104] ProgressIndicator logs "WindowLeaked" exception when hiding dialog and closing window at same time as of 8.0.2
* [TIMOB-27308] Determinant ProgressIndicator ignores "value" property before shown
* [TIMOB-27309] Cannot re-show ProgressIndicator dialog if auto-closed by previous window
* Removed dialog's handleMessage() related code. No longer needed since JS runs on main UI thread.
* added unit test for Ti.UI.Android.ProgressIndicator

Fixes TIMOB-27104, TIMOB-27308, TIMOB-27309
