The identifier of keys created/registred should be in
the application range.
This is by spec for key creation.
This may change for registered key.

The lifetime of key attributes now encodes whether a key is
volatile/persistent or not AND its location.
Fix PSA code where the fact that the lifetime encodes
the key location was not taken into account properly.
Fix the impacted tests and add two non regression tests.

When key identifiers encode key owner, add tests
checking that:
. the key owner of an imported volatile key is
the one specified.
. a key identifier of a volatile key with a valid
PSA key identifier but the wrong owner is
rejected.

Volatile key identifiers in the vendor range are
reserved to volatile keys thus don't allow them
for persistent keys when creating a key.

For persistent keys there were two successive
INVALIDATE_BY_(CLOSING/DESTROYING) identical tests
where the comments of the second test rather
indicated that it should had been an
INVALIDATE_BY_(CLOSING/DESTROYING)_WITH_SHUTDOWN test.

Rename ways of invalidating keys before introducing
key purging tests because the "CLOSE_BY" prefix doesn't
get on well with the purge operation.

As handles are now key identifiers, a handle may be
valid now even if it does not refer to any key
known to the library.

Define psa_key_handle_t to be equal to
mbedtls_svc_key_id_t. Make the handle of a persistent
key be equal to its key identifier. For volatile keys,
make the key handle equal to the volatile key
identifier of the created volatile key.
The unit tests are modified just to make them compile
not to make them run successfully. They are fixed in
the subsequent commits.

The ccm tests were previously relying on unspecified behaviour in
the underlying implementation (i.e. that it rejects certain buffer
sizes without reading the buffer).

The CCM specification (NIST SP 800-38C) mandates that the formatting of
the additional data length l(a) changes when it is greater _or equal_ to
2^16 - 2^8 (>= 0xFF00). Since such lengths are not supported in mbed TLS,
the operation should fail in such cases.
This commit fixes an off-by-one error which allowed encryption/decryption
to be executed when l(a) was equal to 0xFF00, resulting in an
incorrect/non-standard length format being used.
Fixes#3719.

... as opposed to PSA_ERROR_BAD_STATE.
The spec on psa_cipher_finish() states that PSA_ERROR_INVALID_ARGUMENT
should be returned when:
"The total input size passed to this operation is not valid for this
particular algorithm. For example, the algorithm is a based on block
cipher and requires a whole number of blocks, but the total input size
is not a multiple of the block size."
Currently, there is a distinction between encryption and decryption
on whether INVALID_ARGUMENT or BAD_STATE is returned, but this is not
a part of the spec.
This fix ensures that PSA_ERROR_INVALID_ARGUMENT is returned
consistently on invalid cipher input sizes.

* Reworked the cipher context once again to be more robustly defined
* Removed redundant memset
* Unified behaviour on failure between driver and software in cipher_finish
* Cipher test driver setup function now also returns early when its status
is overridden, like the other test driver functions
* Removed redundant test cases
* Added bad-order checking to verify the driver doesn't get called where
the spec says it won't.
