vimage is a kernel option, not a module. It affects the entire kernel, 
and cannot be loaded as a module. It’s either enabled or not (and 
it’s enabled in 12.0).

Yes. It was removed around the time it was enabled by default.

Yes. The automated pf tests rely on vimage.

Yes, assuming you mean pflog output. Log files can of course be read 
from the host.

No. The decision to load the pf module is made by the host. If the 
module is not loaded no jail will be able to use it. Jails may not load 
kernel modules, for obvious reasons.

Yes.
