Add configure and CMake options to define CURL_DISABLE_NEGOTIATE_NTLM,
which gates the NTLM blocking logic in the SSPI and GSS-API SPNEGO
code paths behind a compile-time flag.
Add a 'SPNEGO-no-NTLM' feature string to curl --version output and
gate the SPNEGO NTLM blocking tests on the negotiate-ntlm-disabled
feature.

test2092 verifies that when only NTLM credentials are available and
CURL_DISABLE_NEGOTIATE_NTLM is active, SPNEGO auth is silently skipped
and the request is sent without an Authorization header.
test2093 verifies that Kerberos credentials still succeed when built
with CURL_DISABLE_NEGOTIATE_NTLM.
Both tests require the negotiate-ntlm-disabled feature, which is
reported by curl --version as "SPNEGO-no-NTLM" when the compile-time
option is active.
