drm/i915: Move intel_engine_mask_t around for use by i915_request_types.h

Browse Source 
We want to use intel_engine_mask_t inside i915_request.h, which means
extracting it from the general header file mess and placing it inside a
types.h. A knock on effect is that the compiler wants to warn about
type-contraction of ALL_ENGINES into intel_engine_maskt_t, so prepare
for the worst.

v2: Use intel_engine_mask_t consistently
v3: Move I915_NUM_ENGINES to its natural home at the end of the enum

* Requests exist in a complex web of interdependencies. Each request
* has to wait for some other request to complete before it is ready to be run
* (e.g. we have to wait until the pixels have been rendering into a texture
* before we can copy from it). We track the readiness of a request in terms
* of fences, but we also need to keep the dependency tree for the lifetime
* of the request (beyond the life of an individual fence). We use the tree
* at various points to reorder the requests whilst keeping the requests
* in order with respect to their various dependencies.
*
* There is no active component to the "scheduler". As we know the dependency
* DAG of each request, we are able to insert it into a sorted queue when it
* is ready, and are able to reorder its portion of the graph to accommodate
* dynamic priority changes.
