[hidpi] Use wxWidgets 3.2 on Windows

* Remove the custom handling for pre-3.1.4 builds on Windows since
  both the mingw and msvc builds now use 3.2.
* Remove wxDPIChangedEvent handling, since this triggers a resize,
  which has the same effect.
* Implement main/WinMain ourselves, rather than relying on wxWidgets
  macros. This allows us to initialize the console earlier in the
  process.
* Add an explicit dependency on the manifest file to trigger a link
  when it is modified.
