Aaron Klotz a44687e71f wgengine/winnet: invoke some COM methods directly instead of through IDispatch. ...

Intermittently in the wild we are seeing failures when calling
`INetworkConnection::GetNetwork`. It is unclear what the root cause is, but what
is clear is that the error is happening inside the object's `IDispatch` invoker
(as opposed to the method implementation itself).

This patch replaces our wrapper for `INetworkConnection::GetNetwork` with an
alternate implementation that directly invokes the method, instead of using
`IDispatch`. I also replaced the implementations of `INetwork::SetCategory` and
`INetwork::GetCategory` while I was there.

This patch is speculative and tightly-scoped so that we could possibly add it
to a dot-release if necessary.
