[Android] Update android:minSdkVersion to 19 (KitKat).

This updates the minimum SDK version to 19 (KitKat), which in practice
deprecates supports for Android Jelly Bean (SDK 16, 17, 18).

//components/cronet still needs to support Jelly Bean, so those
manifests are upgraded from SDK level 14 to 16, referring to the meta
bug for Jelly Bean support in cronet.

The WebAPK minSdkVersion will be updated in a different CL.
