…mAsync, SendToAsync Add polyfills for System.Net.Sockets.Socket async methods that are missing on older target frameworks: - ConnectAsync(EndPoint, CancellationToken) - polyfilled for <net5.0 - DisconnectAsync(bool, CancellationToken) - polyfilled for <net6.0 - ReceiveFromAsync(Memory<byte>, SocketFlags, EndPoint, CancellationToken) - polyfilled for <net6.0 - SendToAsync(ReadOnlyMemory<byte>, SocketFlags, EndPoint, CancellationToken) - polyfilled for <net6.0 Also adds SocketReceiveFromResult type polyfill for net461, net462, net47, and uap10.0 which lack the struct natively.

Match BCL's System.Net.Sockets which uses [module: NullablePublicOnly(false)]. Fields become nullable-oblivious, avoiding CS0649 for the never-assigned EndPoint field on internal struct builds. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
Add polyfills for
System.Net.Sockets.Socketasync methods missing on older target frameworks:ConnectAsync(EndPoint, CancellationToken)DisconnectAsync(bool, CancellationToken)ReceiveFromAsync(Memory<byte>, SocketFlags, EndPoint, CancellationToken)SendToAsync(ReadOnlyMemory<byte>, SocketFlags, EndPoint, CancellationToken)Also adds a
SocketReceiveFromResulttype polyfill for net461, net462, net47, and uap10.0.Notes
ApiBuilderTestsshould be re-run to regenerate them officially.
