[PATCH v4 i-g-t 0/2] tests/intel/xe_sriov_flr: Add parallel FLR subtest for SR-IOV VFs

[Marcin Bernatowicz <marcin.bernatowicz@linux.intel.com>]

Introduce a new subtest flr-vfs-parallel to validate parallel FLR
execution on all VFs. This subtest ensures correct behavior during
simultaneous resets.

Introduce the flr-twice subtest, which initiates FLR twice in parallel 
on the same VF. This subtest covers a use case where two FLRs can occur
within a short time frame, such as when starting a QEMU VM with
a passed VF.

v2: Reintroduce condition to reinitialize test data only if more VFs
    remain to be tested (omitted when extracting execute_sequential_flr).
v3: Introduce threaded FLR initiation to achieve better parallelism
    by mitigating 100ms reset delays.(Lukasz)
v4: Use total_flrs variable instead of repeating num_vfs * num_flrs_per_vf
    (Lukasz)
