This optimization doesn't work when the ray query index isn't uniform across
the subgroup, which is something the spec allows. While there are some smart
ways to fix this and still avoid unnecessary spilling, its not worth investing
the time until we find a realtime raytracing workload that actually needs to
use multiple live ray queries for something.

Each node has their own opacity bits, so we don't need to track these
opacity flags at header level.
This commit also fixes the instance flag. Instance flag is 8bit wide,
but we were always using 4 lower bits.

We have no usage of the information returned by
intel_perf_load_configuration(). It is only used to add a copy of the
configuration so we have the metric id but we could instead get the
metric id from sysfs, that is added by mdapi.
Xe KMD don't have a uAPI to query the metrics configuration, so
using sysfs also fixes the integration of mdapi with Xe KMD.

The backend now only deals with load_push_data_intel. load_uniform &

An example when the memory leak happens: requested_size = 4 and alignment = 65536 in anv_slab_bo_alloc:
The alloc_size = 65536 and requested = 4 in this case.
The group to allocate the entry is the group of size 65536 based on the entry size,
while the group to reclaim the entry is the group of size 4 due to the bo->size is
registered as the requested_size=4 and used in anv_slab_bo_free.
That means, the entry is allocated in group[order of size 65535]->free,
moved from group[order of size 65535]->free to the user, and then moved
to group[order of size 4]->reclaim, so the entries is accumulated in
group[order of size 4]->reclaim and group[order of size 65535] keeps
allocating new entries and leading to OOM.
The solution is to use `bo->actual_size` to get the group in pb_slab_bo_free using the allocation size.
