drm/i915: extract i915_perf.h from i915_drv.h It used to be handy that we only had a couple of headers, but over time i915_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes.

drm/i915/selftests: Verify the LRC register layout between init and HW Before we submit the first context to HW, we need to construct a valid image of the register state. This layout is defined by the HW and should match the layout generated by HW when it saves the context image. Asserting that this should be equivalent should help avoid any undefined behaviour and verify that we haven't missed anything important! Of course, having insisted that the initial register state within the LRC should match that returned by HW, we need to ensure that it does. v2: Drop the RELATIVE_MMIO flag from gen11, we ignore it for constructing the lrc image.
