[kmac] Moving KDF struct to KMAC IP

Previously KeyMgr KDF interface was defined in KeyMgr IP. The interface
has been used for KeyMgr to initiate KMAC operation via side channel
interface.

As rom_ctrl and otp_ctrl plan to use KMAC as signature verification
function, KMAC needs to have more general application interface now.

This commit is to move the KDF struct into KMAC and renames it to
`app_{req/rsp}_t`.
