wifi: rtw89: coex: Port _update_bt_ctrl_lps() for BT profile-based LPS control

The old lps_ctrl_scbd logic in _update_bt_scbd() blocked WiFi LPS only
when mode == BTC_WLINK_V0_2G_STA, which created a dead-lock while
WiFi already in LPS suppressed TDD binding so mode was never set to
BTC_WLINK_V0_2G_STA, lps_ctrl_scbd stayed 0, and WiFi remained stuck
in LPS. Port _update_bt_ctrl_lps() from the reference implementation to
check BT profile existence (A2DP, HFP, PAN) for both radios directly,
with out_of_band and freerun guards so LPS is only blocked when WiFi and
Bluetooth actually share a band. Call it from both _update_bt_scbd() and
_update_bt_info() so profile changes reported via either SCBD or BT info
C2H correctly update lps_ctrl_scbd. Also remove the dead
lps_ctrl_scbd_last field.
