Make autotools and cmake detect DES support in OpenSSL and mbedTLS.
Forward feature macros to C and omit NTLM from the feature preview list.
Use the feature macros in source. This ensure that -V output matches
the preview.

OpenSSL doesn't support DES when built with no-des or no-deprecated.
mbedTLS 4.x no longer supports it, and it's possible to disable it in
<4 with scripts/config.py unset MBEDTLS_DES_C.

Before this patch this worked for
mbedTLS 4 only, and with a regression for pending PR #16973.

Also:

• drop NTLM feature check from curl_setup.h in favour of autotools/
  cmake feature macros. This makes curl_setup.h no longer need
  to include an mbedTLS header, which in turn makes tests/server build
  without depending on mbedTLS.
  Fixing, in cmake: define dependencies as IMPORTED interface targets #16973:

  In file included from tests/server/first.h:40,
                   from bld/tests/server/servers.c:3:
