[PATCH v3 06/23] drm/xe/log: Add SIGID log helpers for location

We can determine the location of the SIGID error source based on the
type of the xe pointer being currently available. Add helper macros
that will accept any of xe_device, xe_tile or xe_gt pointers instead
of plain pci_dev to generate valid XE_LOG_LOCATION identifier and then
call low-level xe_log_emit(pdev) function.
