wifi: rtw89: add related H2C for WoWLAN mode

In this patch we define some H2C, which will be called during suspend
flow, to enable WoWLAN function provided by WoWLAN firmware.

These H2C includes keep alive used to send null packet to AP periodically
to avoid being disconnected by AP, disconnect detection used to configure
how we check if AP is offline, wake up control used to decide which WiFi
events could trigger resume flow, and global control used to enable WoWLAN
function.
