wifi: iwlwifi: mvm: prepare the introduction of V9 of REDUCED_TX_POWER

Browse Source 
* Rename iwl_dev_tx_power_cmd to iwl_dev_tx_power_cmd_v3_v8
* struct iwl_dev_tx_power_common needs to be packed. It was always the
  case, but now that its size is not a multiple of 4, it becomes
  meaningful.
* Move per_band data out of the common structure since it won't be
  present in the new versions of the command.
