Add SystemApis to expose runtime profile information 

The API allows a system apps which acquired
{@code android.permission.READ_RUNTIME_PROFILE} to snapshot the runtime
profiles of installed packages.

The API is implemented in a new service class (AndroidRuntimeManager)
accessible from the context using
context().getPackageManager().getAndroidRuntimeManager().

The main functionality is exposed as a one way call into the
AndroidRuntimeManager with the result being posted on a callback. The
profile is available to the caller as a read-only ParcelFileDescriptor.

This CL only adds the API interfaces and validation. It does not fully
implement the functionality.

oneway void snapshotRuntimeProfile(in String packageName,
  in String codePath, in ISnapshotRuntimeProfileCallback callback)

(cherry picked from commit 45f8b29c)
