apps/openssl: add -propquery command line option

Fixes #13656. Right now all openssl commands use a NULL propq. This
patch adds a possibility to specify a custom propq.

The implementation follows the example of set_nameopt/get_nameopt.

Various tools had to be modified to call app_get0_propq after it has
been populated. Otherwise the -propquery has no effect.

The tests then verify the -propquery affects the tool behaviour by
requesting a non-existing property.
