openssl: Wire up dynamic engine build goo.

This restores the devcrypto engine, which was converted from static
to dynamic since the previous OpenSSL update.

XXX Pretty sure I got some of the set list package names wrong, but
it's not clear what the right ones are or what consequences any of
this has.

XXX Needs testing.

Revert "openssl: Nix build goo for dynamically loaded engines."

Turns out there is a regression lurking here: the devcrypto engine
was made dynamic-only (https://github.com/openssl/openssl/pull/7859),
so to maintain that functionality, we need to build dynamic engines.
Will fix the aarch64 build issue and wire things up separately.

openssl: Nix build goo for dynamically loaded engines.

- Engines are deprecated in openssl 3.

- We never actually had the .so engines wired up to be built in
openssl 1.1, and judging by the lack of obsolete entries in the set
lists, I don't think we ever had them wired up to be built at all.

branches: 1.1.2; 1.1.4;
Add engines infrastructure, not hooked to the build:
1. sets needs to be fixed
2. need to decide if I am going to add engine.so.MAJOR or use engine.so
like OpenSSL wants
3. padlock is MD (x86) needs asm to be added, and conditionally built
