Restructure NegotiateAuthentication implementation (#87930)
* Change NegotiateAuthentication implementation to use indirection through NegotiateAuthenticationPal to the actual implementation. The PAL implementation are merged from different sources to follow the same structure: - NTAuthentication.Managed.cs -> NegotiateAuthenticationPal.Managed.cs - NTAuthentication.Common.cs + NegotiateStreamPal.Windows.cs -> NegotiateAuthenticationPal.Windows.cs - NTAuthentication.Common.cs + NegotiateStreamPal.Unix.cs -> NegotiateAuthenticationPal.Unix.cs This split allows to delete ContextFlagsPal, SafeDeleteNegoContext, and SafeFreeNegoCredentials abstractions that were used in NegotiateStreamPal. * Unify impersonation level validation between Windows and Unix pllatforms * Split managed NTLM and managed SPNEGO implementations; add UseManagedNtlm switch on Unix platforms * Remove debug cruft * Fix couple of errors in managed SPNEGO * Remove debug print * Fix message sequence in managed NTLM; remove unused method * Fix fallbacks on macOS GSSAPI * Cleanup and fallbacks for missing NTLM, GSSAPI * Adjust tests to assume that NTLM is always available on Unix * Don't claim NTLM support on Browser * Revert "Don't claim NTLM support on Browser" This reverts commit 87d0c56. * Attempt to fix the browser tests * Revert "Attempt to fix the browser tests" This reverts commit 91d7ce2. * Browser test suppression * Respect UseManagedNtlm=false on platforms without NTLM GSSAPI provider * Update src/libraries/System.Net.Security/src/System/Net/NegotiateAuthenticationPal.Unix.cs * Revert all the fallback code paths, System.Net.Security.UseManagedNtlm has to be enabled explicitly; NativeAOT on Linux Bionic does that by default because it doesn't have GSSAPI and native shim
