It is using system APIs, but we might want to update it via the play
store.
Hence, replace all internal APIs used with support lib APIs. There is
no replacement for @Immutable, but this is just a informational
annotation, so it can just be removed.
As system-api is tied to a specific platform version, remove all
minSDK/targetSDK settings in the manifest.

Fixes: 78162439
Test: Looked at print service recommendations
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
