void PrepareHeadersIn (TxFrame & aTxFrame)Prepares MAC headers based on `BuildInfo` fields in a given `TxFrame`.
This method uses the `BuildInfo` structure to construct the MAC address and security headers in
It determines the Frame Control Field (FCF), including setting the appropriate frame type, security level,
and addressing mode flags. It populates the source and destination addresses and PAN IDs within the MAC
header based on the information provided in the `BuildInfo` structure.
It sets the Ack Request bit in the FCF if the following criteria are met:
- A destination address is present
- The destination address is not the broadcast address
- The frame type is not an ACK frame
The header IE entries are prepared based on `mAppendTimeIe` and `mAppendCslIe` flags and the IE Present
flag in FCF is determined accordingly.
The Frame Pending flag in FCF is not set. It may need to be set separately depending on the specific
requirements of the frame being transmitted.
