In the driver wrapper for psa_generate_key() and psa_generate_key_ext():
* Invoke the built-in code if using a non-default method, even if there
might be an accelerator. This is ok because we only support non-default
methods for RSA and we don't support driver-only RSA, therefore a
non-default method will always have built-in code behind it.
* Return NOT_SUPPORTED if trying to use a non-default method with an opaque
driver.

Instead of passing the size of the whole structure, just pass the data
length and let the implementation worry about adding the size of the
structure. The intent with passing the structure size was to allow
the client code in a client-server implementation to know nothing
about the structure and just copy the bytes to the server. But that was not
really a useful consideration since the application has to know the
structure layout, so it has to be available in the client implementation's
headers. Passing the method data length makes life simpler for everyone by
not having to worry about possible padding at the end of the structure, and
removes a potential error condition
(method_length < sizeof(psa_key_generation_method_t)).

All paths in both switch statement lead to a return, therefore the
end block in both of these functions can never be reached. Fix this by
making sure the end block is always called (set status rather than just
return), as its safer for future changes. Found by coverity scan.

CryptGenRandom and lstrlenW are not permitted in Windows Store apps,
meaning apps that use mbedTLS can't ship in the Windows Store.
Instead, use BCryptGenRandom and wcslen, respectively, which are
permitted.
Also make sure conversions between size_t, ULONG, and int are
always done safely; on a 64-bit platform, these types are different
sizes.
Also suppress macro redefinition warning for intsafe.h:
Visual Studio 2010 and earlier generates C4005 when including both
<intsafe.h> and <stdint.h> because a number of <TYPE>_MAX constants
are redefined. This is fixed in later versions of Visual Studio.
The constants are guaranteed to be the same between both files,
however, so we can safely suppress the warning when including
intsafe.h.

Now that p256-m is officially a production feature and not just an example,
give it a more suitable name.

Transparent drivers don't have this entry points. Other entry points
that are only for opaque drivers are not listed here but only in the
opaque_driver.json file, so this was likely a mistake.

The support for the PSA crypto driver interface
is not optional anymore as the implementation of
the PSA cryptography interface has been restructured
around the PSA crypto driver interface (see
psa-crypto-implementation-structure.md). There is
thus no purpose for the configuration options
MBEDTLS_PSA_CRYPTO_DRIVERS anymore.

Move the global variable to the PSA layer, and just set that when calling PSA
level functions.
Move the internal ecp set to before each ecp call.

Adapt pake test (passing NULL buffers is not allowed).
Passing the null buffer to psa_pake_output results in a hard fault.

- Add `alg` and `computation_stage` to `psa_pake_operation_s`.
Now when logic is moved to core information about `alg` is required.
`computation_stage` is a structure that provides a union of computation stages for pake algorithms.
- Move the jpake operation logic from driver to core. This requires changing driver entry points for `psa_pake_output`/`psa_pake_input` functions and adding a `computation_stage` parameter. I'm not sure if this solution is correct. Now the driver can check the current computation stage and perform some action. For jpake drivers `step` parameter is now not used, but I think it needs to stay as it might be needed for other pake algorithms.
- Removed test that seems to be redundant as we can't be sure that operation is aborted after failure.
