app/internal/window: [Android] use correct JNI Call variant for registerFragment

Browse Source 
While we're here,

- replace the registerFragment trampoline with a general variadic
CallVoidMethod trampoline.
- Use UTF-16 for passing strings to Java. Java's modified UTF-8 encoding differ
from Go's in corner cases.
