Fixed builds for DreamSDK4.

- Both Miami and Liberty fixed.
- FUNDAMENTAL issues with data types not being configured correctly for
  64-bit Windows
- More issues with <windows.h> and other files not being included
  properly for _WIN64
- Successfully baked and tested both liberty and miami CDIs in Flycast
