wifi: rtw89: send OFDM rate only in P2P mode

Check IEEE80211_TX_CTL_NO_CCK_RATE flag to avoid sending frames with
CCK rates in 2GHz band.

In TX flow, add IEEE80211_TX_CTL_NO_CCK_RATE flag to check and get its
lowest rate without CCK rates if the TX type is mgmt frames or data frames.
Besides, the decision of phy rate and retry rate in P2P mode are also
be handled.

In P2P GO mode, it should send beacon of no CCK rates in its frame rate.
Therefore, We add a condition to decide which rate is added to beacon
content.

Moreover, we avoid setting a mask of rates to be used for rate control
selection before and after connection in P2P mode.
