Split out CMAC and HMAC code into auxiliary functions
...
Split algorithm-specific code out of psa_mac_start. This makes the
function easier to read.
The behavior is mostly unchanged. In a few cases, errors before
setting a key trigger a context wipe where they didn't. This is a
marginal performance loss but only cases that are an error in caller
code.
