Implement support for volatile keys in a secure element. #3302 defines an encoding of lifetimes that makes certain keys volatile, but the code does not treat them as volatile.

This is part of a larger redesign in #3287 and should not necessarily be implemented on its own with the current structure of the code.

Goals:

  • Support volatile keys in a secure element, in addition to persistent keys.
  • At least smoke tests. Detailed testing is out of scope of this task.
