Drop SupportedOSPlatform gates; SDK now runs on Linux

The dialect / orchestrators were defensively gated on Windows because
HistorianSspiClient previously P/Invoked InitializeSecurityContextW. With
that replaced by NegotiateAuthentication (cross-platform), the gates are
unnecessary. Removed them from:

- Historian2020ProtocolDialect (4 read paths + 3 status helpers)
- HistorianClient.EnsureTagAsync / DeleteTagAsync
- HistorianWcf{Auth,Read,Event,Status,TagWrite}Orchestrator/Helper
- HistorianWcf{HistAddressing,MessageCapture}Behavior
- HistorianWcfBindingFactory (with #pragma on the Named-Pipe builder
  which still requires Windows at the BCL level)

Runtime constraint: LocalPipe and RemoteTcpIntegrated transports still
require Windows because NetNamedPipeBinding and the Windows transport
security binding are Windows-only at the BCL level. RemoteTcpCertificate
is now usable from Linux, and ProbeAsync is verified working from a
Debian client (10.100.0.35) against the Windows Historian (10.100.0.48).

171/171 tests still pass on Windows.
