drm/xe/client: Print runtime to fdinfo

Print the accumulated runtime for client when printing fdinfo.
Each time a query is done it first does 2 things:

1) loop through all the exec queues for the current client and
accumulate the runtime, per engine class. CTX_TIMESTAMP is used for
that, being read from the context image.

2) Read a "GPU timestamp" that can be used for considering "how much GPU
time has passed" and that has the same unit/refclock as the one
recording the runtime. RING_TIMESTAMP is used for that via MMIO.

Since for all current platforms RING_TIMESTAMP follows the same
refclock, just read it once, using any first engine available.

This is exported to userspace as 2 numbers in fdinfo:

drm-cycles-<class>: <RUNTIME>
drm-total-cycles-<class>: <TIMESTAMP>

Userspace is expected to collect at least 2 samples, which allows to
know the client engine busyness as per:

RUNTIME1 - RUNTIME0
busyness = ---------------------
T1 - T0

Since drm-cycles-<class> always starts at 0, it's also possible to know
if and engine was ever used by a client.

It's expected that userspace will read any 2 samples every few seconds.
Given the update frequency of the counters involved and that
CTX_TIMESTAMP is 32-bits, the counter for each exec_queue can wrap
around (assuming 100% utilization) after ~200s. The wraparound is not
perceived by userspace since it's just accumulated for all the
exec_queues in a 64-bit counter) but the measurement will not be
accurate if the samples are too far apart.

This could be mitigated by adding a workqueue to accumulate the counters
every so often, but it's additional complexity for something that is
done already by userspace every few seconds in tools like gputop (from
igt), htop, nvtop, etc, with none of them really defaulting to 1 sample
per minute or more.
