Subject: [PATCH 1/2] Fix FIPS mode support and build with OpenSSL 3.0

FreeRDP fails to build with OpenSSL 3.0 because of usage of the `FIPS_mode`
and `FIPS_mode_set` functions, which were removed there. Just a note that
the FIPS mode is not supported by OpenSSL 1.1.* although the mentioned
functions are still there (see https://wiki.openssl.org/index.php/FIPS_modules).
Let's make FreeRDP build with OpenSSL 3.0 and fix the FIPS mode support.

See: https://bugzilla.redhat.com/show_bug.cgi?id=1952937
