Fixes #3650. This removes the bad call to `FreeLibrary` that was still present in a callee of `DllMain` in keyman32. The refactor moves responsibility for loading TSF to the `SelectKeyboard` functions and gets rid of the associated thread globals. The `TSFINTERFACES` struct is of course a future candidate for a class. In the process I removed a lot of cruft from keyman32.cpp which was either obsolete, irrelevant or just plain wrong. None of which had material impact on the running code.
