WIN run main thread redirects ignoring SolarMutex

This way we can drop all the special nReleased handling. Instead
we use the same mechanism as on Mac, where we keep the lock, but
disable it for the main thread. As a security measure we assert on
duplicate redirects, which should not happen.

As a result we can't use SendMessage on the main thread itself,
which would normally just call the WinProc directly. This could be
accomplished by converting the redirect bool into a counter, which
should be safe, as no other thread could acquire the SolarMutex,
as we don't release it.
