82df32e3fd psa: Unused key_bits is OK 
When MD or CMAC are disabled, let the compiler know that it is OK that
`key_bits` is set but not used by casting `key_bits` to `(void)`.

remove unneeded variables and use shared utilities where possible.

688ea8d10d pk_wrap: reuse a static buffer for signature extraction

3016de3eeb pk_wrap: rework signature extraction to work with small r and s values 
There is a probability that r will be encoded as 31 or less bytes in DER,
so additional padding is added in such case.
Added a signature-part extraction function to tidy up the code further.

29a1325b0d Guard against PSA generating invalid signature 
The goal is not to double-check everything PSA does, but to ensure that it
anything goes wrong, we fail cleanly rather than by overwriting a buffer.

1e48ebd306 Fix a compliance issue in signature encoding

automatically, but we're not using that here...

276cb64e6c Align names to use "opaque" only everywhere 
It's better for names in the API to describe the "what" (opaque keys) rather
than the "how" (using PSA), at least since we don't intend to have multiple
function doing the same "what" in different ways in the foreseeable future.

07b103fe07 Implement can_do for opaque ECC keypairs 
Unfortunately the can_do wrapper does not receive the key context as an
argument, so it cannot check psa_get_key_information(). Later we might want to
change our internal structures to fix this, but for now we'll just restrict
opaque PSA keys to be ECDSA keypairs, as this is the only thing we need for
now. It also simplifies testing a bit (no need to test each key type).
