Renamed to avoid the seemingly redundant 'context_' infix and note that it's been reviewed by Matthew Auld.

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.
