wifi: ath10k: Support for FTM TLV test commands

Existing tools like myftm use 'legacy' test command API. Similarly
to ath11k and ath12k, we want to support raw TLV payload submitted
from the test tool. This requires segmenting the TLV payload and
encapsulating it within a WMI command. The opposite operation needs
to be done upon corresponding event receiving.
