openssl: backport devcrypto changes from master

The patches to the /dev/crypto engine were commited to openssl master,
and will be in the next major version (3.0).

Changes:
- Optimization in computing a digest in one operation, saving an ioctl
- Runtime configuration options for the choice of algorithms to use
- Command to dump useful information about the algorithms supported by
  the engine and the system.
- Build the devcrypto engine as a dynamic module, like other engines.

The devcrypto engine is built as a separate package by default, but
options were added to allow building the engines into the main library.
