msm8996-common: Add pocketmode app

Change-Id: I71e47d5f203adb7e28d37447e19a8041a1d02840

msm8996-common: PocketMode: Apply LineageOS rebrand

Change-Id: I1de627062f56bd125f430033e8bb7aad8fe48f69

msm8996-common: pocketmode: Bump sdk version

Change-Id: Ic521e380868bdc886e15c6a8a472564a98dbc094

msm8996-common: PocketMode: Explicitly include Android support libs

 * Fixes non-jack build

Change-Id: I9d8346193577c7be218e12efb20f52ca9946eb14

msm8996-common: PocketMode: Properly depend on Lineage SDK

 * This is actually the proper library to include
   (only spotted while buidling with Jack disabled,
   because app compilation was failing).

Change-Id: Ib61f93704c6411a4cb1f91d9e8693a1775934037

msm8996-common: PocketMode: Remove useless cast

Change-Id: I655b0b80ccafdaae422a2464d2b8409f70be0e8c

msm8996-common: Adapt to Zuk

Change-Id: I9050faac37de0a8392b31fed5c3562d4553c546f

msm8996-common: Set LOCAL_SDK_VERSION where possible.

This change sets LOCAL_SDK_VERSION for all packages where
this is possible without breaking the build, and
LOCAL_PRIVATE_PLATFORM_APIS := true otherwise.

Setting one of these two will be made required soon, and this
is a change in preparation for that. Not setting LOCAL_SDK_VERSION
makes the app implicitly depend on the bootclasspath, which is
often not required. This change effectively makes depending on
private apis opt-in rather than opt-out.

Test: make relevant packages
