Check whether to skip a BSS in RNR with a shared helper

Use a shared helper function for this to avoid having to maintain two
copies of the same implementation and the risking those getting out of
sync.
RNR formation for co-location or MLO did not work as expected. Fix this.
For example, during co-location, if the BSS is also its ML partner
there is no need to include a separate TBTT for it.
Also, during co-location, if the BSS is not its partner but it is ML
capable, the TBTT length should be 16 bytes and it should include the
MLD Parameters for it in the RNR.
During co-location, for a given Neighbor AP (operating on a given
channel and op-class) if it has BSSs which are ML capable as well as
BSSs which are not, there should be two Neighbor AP Info present: one
indicating TBTT length as 13 bytes and one indicating TBTT info length
as 16 bytes.
Whenever a BSS was set up,hostapd flushed all stations via the flush()
driver operation which maps to NL80211_CMD_DEL_STATION in the nl80211
interface. However, in case of MLO, a station could have been connected
to other links by the time this link is coming up. Since link ID was not
passed to flush(), all those stations entries were also removed in the
driver which is wrong.
Include the link ID along with the command in AP MLD so that the driver
can use this link ID and flush only the stations that use the passed
link ID as one of their links.

If the driver provides an identifying cookie value for scan operations,
use that to select which link processes the scan result. This is needed
for OBSS scans that can be required in different links if operating as
an AP MLD. Distinguish the scans using scan_cookie for QCA vendor scan
events.

AP MLD: Find the link that is waiting for scan events
In AP MLD case, HT scan results need to be handled in the link that
triggered this scan. So find the link that has a valid scan_cb to handle
EVENT_SCAN_RESULTS.

PASN: Add set and get API for PASN data context
Modules that use libpasn for PASN authentication need the context of
PASN data. PASN data is a common context for the library and the modules
using it. Hence, initialize the context through init and deinit
functions. Also use set and get functions to update the parameters.
Replace PMKSA cache inline stubs with wrapper function stubs
PMKSA cache API is included in libpasn.so used by external modules,
e.g., Wi-Fi Aware. To avoid dependency on IEEE8021X_EAPOL define for the
external modules at compile time, remove PMKSA cache static inline
functions from the header file and add wrapper function stubs.
