This is defined in NIST SP 800-208 as the truncation to 192 bits of
SHA256. Unlike other truncated hashes in the SHA2 suite, this variant
doesn't have a different initial state, it is just a pure truncation
of the output.

The provider- manuals are meant to describe the general interface for
their respective operation. This is not the place to describe
implementation specific details.
This change creates a number of doc/man7/EVP_MD manuals, one for each
algorithm or set of algorithms, as well as doc/man7/EVP_MD-common.pod
to describe what's common to them all.
While we're at it, correct the SHA3 settable context params array to
match what's actually settable.
