The target attributes for key copy could have key bits and
type zeroed. If so, they need to be overwritten/ inherited
from the source key.
This is now forcefully overwritten after validating the
optional attributes. As a result assigning attributes type
and bits after copy are no longer necessary.

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.

The validation against key width and max key bits is extended to
all key types from the existing validation for only symmetric keys.

-Add test driver support to import/export while wrapping keys
meant to be stored in the PSA core as opaque( emulating an
SE without storage ).
-Export validate_unstructured_key_bit_size as
psa_validate_unstructured_key_bit_size, thereby changing its scope.
-Improve the import/export test cases in test_suite_psa_crypto to also
cover opaque keys, thereby avoiding duplication.

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.

The report of RSA public exponent for opaque keys is not
supported. Do not attempt to compute the RSA public
exponent of an RSA opaque key associated to a driver
implementing the new driver interface when
MBEDTLS_PSA_CRYPTO_SE_C is disabled.

Slot number key attribute is specific of dynamically
registered drivers and should thus not be computed/
returned in case of keys associated to drivers
implementing the new unified driver interface.

Clarify the purpose of

define it even when MBEDTLS_PSA_CRYPTO_SE_C is disabled
for the purpose of static drivers.

To improve readability by saving horizontal and vertical space.
Removed unecessary & 0xFF.
Byte reading macros implemented in library/common.h, All files
containing "& 0xff" were modified.
Comments/Documentation not yet added to the macro definitions.

The error is currently never returned to any function that PSA calls,
but keep mbedtls_to_psa_error up to date in case this changes.

Introduce psa_mac_compute_internal with an
additional `is_sign` parameter compared to
the psa_mac_compute API. The intent is to
call psa_mac_compute_internal() from
psa_mac_verify() as well to compute the
message MAC.

Re-organize psa_mac_setup() to prepare the move
to a dedicated function of the additional checks
on the algorithm and the key attributes done by
this function. We want to move those checks in
a dedicated function to be able to do them
without duplicating them in psa_mac_compute().

This makes it easier to ensure that crypto_spe.h is included everywhere it
needs to be, and that it's included early enough to do its job (it must be
included before any mention of psa_xxx() functions with external linkage,
because it defines macros to rename these functions).
