wifi: rtw89: coex: Fix Bluetooth link weight not updated on profile change

_update_bt_link_cnt() was missing the bt->link_weight[].
Without it, link_weight stays at the initial value of 5
(set on BT re-enable) regardless of the active BT profile.

_set_bind_info() uses link_weight to compute b2g_score/b5g_score, which
determines tdd_bind.rf_band. With a stale weight of 5 (below the active
profile threshold), tdd_bind.rf_band may not reflect the actual RF band,
causing mode_v0 in _run_coex() to remain 0 (BTC_WLINK_NOLINK), which
incorrectly triggers _action_wl_nc() instead of the BT-profile action.

Add the link_weight calculation to _update_bt_link_cnt() using the same
weighting table as Formal (BIS/A2DP-sink: 70, A2DP: 40-60, PAN/active: 30,
no-profile: 5, else: 9) and call _update_bt_link_cnt() from
_update_bt_info() after parsing the profile exist flags, replacing the
open-coded link_cnt increment that omitted le-audio profiles.
