intel: Add a getter for the intel_context ctx_id
Exposing the u32 context ID makes it possible to define new drm kernel interfaces based on the same IDs that e.g. execbuf uses to identify a gem context, that aren't themselves abstracted by libdrm but need to be used by libdrm/drm_intel_context based clients such as (parts of) i-g-t or Mesa. For example this can be used to configure an i915-perf stream to collect metrics for a specific context. v2: s/drm_intel_gem_context_get_context_id/drm_intel_gem_context_get_id/ Signed-off-by: Robert Bragg <robert@sixbynine.org> Reviewed-by: Matthew Auld <matthew.auld@intel.com>main
