wifi: rtw89: coex: Add v4 version firmware cycle report
To support v4 version firmware cycle report, apply the related
structure and functions. v4 cycle report add a group of status
to show how the free-run/TDMA training goes to. It is a firmware
mechanism that can auto adjust coexistence mode between TDMA and
free run mechanism at 3 antenna solution.
