java_device_for_host and java_host_for_device allow treating a device module as a host module and vice versa. They will be useful for converting layoutlib and robolectric to Soong, as these modules run device java code on the host. Bug: 117920228 Test: device_host_converter_test.go Change-Id: Ia9a371fb41a97bc16338097f3ce8b40099744167
