Error out if a driver tries to store more than ITS can handle
...
Cast explicitly for the sake of MSVC which otherwise (usefully!) warns
about the truncation.

SE drivers: implement persistent storage
...
Store the persistent data of secure element drivers.
This is fully implemented, but not at all tested.

SE keys: support destroy

method and update the driver's persistent data in storage.

SE driver lookup functions
...
Expose the type of an entry in the SE driver table as an opaque type
to other library modules. Soon, driver table entries will have state,
and callers will need to be able to access this state through
functions using this opaque type.
Provide functions to look up a driver by its lifetime and to retrieve
the method table from an entry.

Gate secure element support by a separate config option
...
Secure element support has its own source file, and in addition
requires many hooks in other files. This is a nontrivial amount of
code, so make it optional (but default on).
