Keep InCallUI in memory (1/3)

In lower end devices, startup of the InCallUI process can take
up to 10 seconds when the device is busy, which prevents the user
from taking the call. Keep the process in memory like previous
versions where they are a part of Phone.apk.

This converts InCallUI into a dummy apk with the persistent
attribute set to true and allows the activity from Dialer.apk,
which uses the com.android.incallui process to be loaded into the
persistent process.

Revert "Make incall screen glopad background themeable"

Change I6a0a120662e4e45b5282a763c8ccf41d29c6d470 was supposed
to make only bottom half of caller photo semi-transparent. Instead
it also exposes in-call buttons at the bottom of the screen behind
the glowpad. This has looked plain broken for months.

This reverts commit 3073f8760c82198a80cf8efe3fe0e3b2804852c2.
