intel/common/xe: Re implement xe_gem_read_render_timestamp() with xe_gem_read_correlate_cpu_gpu_timestamp()

Browse source 
With the removal of DRM_IOCTL_XE_MMIO xe_gem_read_render_timestamp()
was always returning false but with DRM_XE_DEVICE_QUERY_ENGINE_CYCLES
it can be re implemented making use of
xe_gem_read_correlate_cpu_gpu_timestamp().
