ebiten: add APIs to treat monitors (#2597)
This change adds these APIs:

* `type MonitorType`
* `func (*MonitorType) Bounds() image.Rectangle`
* `func (*MonitorType) Name() string`
* `func Monitor() *MonitorType`
* `func SetMonitor(*MonitorType)`
* `func AppendMonitors([]*MonitorType) []*MonitorType`

Closes #1835
