Bug 1231: Add Windows x86_64 test executable ; Use 'WinMain' for Windows test-executable ; Use CustomInflate for Performance

- Use 'WinMain' for Windows test-executable
  This may have little difference than using std 'main' entry

- Add Windows x86_64 test executable
  Since the reporter claims the test executable works well
  on Windows i386, maybe utilizing a x86_64 test executable
  on same VM fixes the issue

- Use CustomInflate for Performance
  - Skips GZIP header
  - Adds own custom header [magic, deflate-size, inflate-size]
  - Own header allows simplified I/O read and deflation
