wifi: iwlwifi: pass ESR parameters to the firmware
The firmware needs to know the esr_transtition_timeout to time the
transition between EMLSR and single radio with the AP.
Add the EMLSR support bit to the wiphy extended capabilities so that
it'll be sent in our association request frame. There are some
limitations in the implementation so we cannot use zero
padding/transition delay; fill the correct values.
Also, feed the medium_synchronization delay to the firmware.
