intel: Add intel_gem_create_context_engines

Browse Source 
Engines based contexts operate somewhat different for executing
batches. Previously, we would specify a bitmask value such as
I915_EXEC_RENDER to specify to run the batch on the render ring.

With engines contexts, instead this becomes an array of "engines", and
when the context is created we specify the class and instance of the
engine.

Each index in the array has a separate hardware-context. Previously we
had to create separate kernel level contexts to create multiple
hardware contexts, but now a single kernel context can own multiple
hardware contexts.

Another forward looking advantage to using the engines based contexts
is that the kernel does not plan to add new supported I915_EXEC_FOO
masks, whereas they instead plan to add new I915_ENGINE_CLASS_FOO
engine classes. Therefore some rings may only be usable with an engine
based class.
