[mac] put transmission AES-CCM* to SubMac layer (#4919)

Browse Source 
In Thread 1.2, it is possible to receive an IEEE 802.15.4-2015
packet. Per specification, receiver should acknowledge this packet
with an IEEE 802.15.4-2015 ACK(Enh-ACK). This Enh-ACK can include
header IE with it and requires security enabled bit in FCF be set to
true. It is impractical for the host to generate the Enh-ACK and send
to RCP for transmission within AIFS time(192us). So RCP should prepare
the Enh-ACK by itself, which requires it to fill in the frame counter
and do the encryption/authentication. This commit tries to address the
need of transmission security/authentication by including the
following changes,

- Move Key ID mode 1 AES-CCM* related functions from MAC layer to
  SubMac layer, which is mirrored in RCP.

- Distribute the MAC key and MAC key ID to RCP in posix app using
  newly added spinel properties.

- Make it possible for radio(either in radio driver or hardware) to do
  transmission AES-CCM* if the platform supports by adding radio
  capability OT_RADIO_CAPS_TRANSMIT_SEC.

- Enable this for RCP mode on simulation platform.
