Hajime Hoshi 2c2c4bc428 ebiten: add WindowResizingModeType and its constants and functions
This allows a new state to disallow resizing the window but allow
making the window fullscreen on macOS by a user.

This change adds the new type WindowResizingModeType. There are
these constants of this type:

 * WindowResizingModeDisabled
 * WindowResizingModeOnlyFullscreenEnabled
 * WindowResizingModeEnabled

Closes #1819
