TLS 1.3 and DTLS 1.2 + CID hide the real content type of a record
within the record's inner plaintext, while always using the same
content type for the protected record:
- TLS 1.3 always uses ApplicationData
- DTLS 1.2 + CID always uses a special CID content type.
This commit enhances the record encryption unit test to check
that the record content type is indeed correctly hidden.

The internal functions
`ssl_cid_{build/parse}_inner_plaintext()`
implement the TLSInnerPlaintext mechanism used by DTLS 1.2 + CID
in order to allow for flexible length padding and to protect the
true content type of a record.
This feature is also present in TLS 1.3 support for which is under
development. As a preparatory step towards sharing the code between
the case of DTLS 1.2 + CID and TLS 1.3, this commit renames
`ssl_cid_{build/parse}_inner_plaintext()`
to
`ssl_{build/parse}_inner_plaintext()`.

Now that lifetimes have structures and secure element drivers handle
all the lifetimes with a certain location, update driver registration
to take a location as argument rather than a lifetime.

Applications need this to combine implementation-specific values of
persistence levels and location indicators.

Call persistence "default" because that is genuinely the default that
applications should use if they don't know better. It's slightly
misleading in that the default persistence when you create a key is
volatile, not this: "default" is the default persistence for
persistent keys, not the default persistence for keys in general. But
we haven't found a better name.
Introduce the term "primary local storage" to designate the default
storage location.
