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)
