mac80211_hwsim: add PMSR abort support via virtio

PMSR (a.k.a. peer measurement) is generalized measurement between two
devices with Wi-Fi support. And currently FTM (a.k.a. fine time
measurement or flight time measurement) is the one and only measurement.

Add necessary functionalities for mac80211_hwsim to abort previous PMSR
request. The abortion request is sent to the wmedium where the PMSR request
is actually handled.

In detail, add new mac80211_hwsim command HWSIM_CMD_ABORT_PMSR. When
mac80211_hwsim receives the PMSR abortion request via
ieee80211_ops.abort_pmsr, the received cfg80211_pmsr_request is resent to
the wmediumd with command HWSIM_CMD_ABORT_PMSR and attribute
HWSIM_ATTR_PMSR_REQUEST. The attribute is formatted as the same way as
nl80211_pmsr_start() expects.
