Add a facility to configure entropy sources
...
Add a function to configure entropy sources. For testing only.
Use it to test that the library initialization fails properly if there is no
entropy source.

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)`.

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.

Add tests for ECDSA verify with short r, s values
...
This is intended to test transcoding the signature to the format expected by
PSA (fixed-length encoding of r, s) when r and s have respectively:
- full length with initial null byte
- full length without initial null byte
- non-full length with initial null byte
- non-full length without initial null byte
The signatures were generated using:
programs/pkey/pk_sign tests/data_files/server5.key foo
where foo is an empty file, and with a variant of one of the following patches
applied:
