Allow the user to specify a local engine index (as opposed to class:index) that they can use to refer to a preset engine inside the ctx->engine[] array defined by an earlier I915_CONTEXT_PARAM_ENGINES. This will be useful for setting SSEU parameters on virtual engines that are local to the context and do not have a valid global class:instance lookup. Note that due to the ambiguity in using class:instance with ctx->engines[], if a user supplied engine map is active the user must specify the engine to alter by its index into the ctx->engines[].
