Add opaque test driver support for copy key
A minimal test driver extension is added to support
copy of opaque keys within the same location.
Test vector support is extended to cover opaque keys.

Sizing of key buffer for opaque keys
Create a new sizing function for determining the size required for key
storage based on the input key data.
This is required for key imports where the key length might need to be
derived from the data.

dbf8ceda54 Change the way driver context structures are used
Apparently there's a goal to make the PSA Crypto core free from
dynamic memory allocations. Therefore, all driver context structures
need to be known at compile time in order for the core to know their
final size.

This change defines & implements for hashing operations how the context
structures get defined.

8328287956 psa: Move from validate_key to import_key entry point
In the course of the development of the PSA unified
driver interface, the validate_key entry point for
opaque drivers has been removed and replaced by an
import_key entry point. This commit takes into account
this change of specification.
