COMPMID-2204: RuntimeContext interface for NEON functions.

This patch creates the interfaces for the runtime context for NEON.

Only the Neon backend implements the context which currently only holds
an instance of the scheduler.

The NEActivationLayer function has been updated to use the new context
interface and the corresponding validation tests ported.
