[android] - fixup MyLocationView heading (#6671)

[android] - convert angles to radiants in jni, correct follow animation for MyLocationView

do not sanitise input when recreating from other camera object, input is already sanitised before

cleanup mylocationview, made animation bit more smooth, improved UX when switching between tracking modes

cleanup CameraUpdateFactory, hide internally used api.

only invalidate position if required, remove outdated comments

correct camera position values

made zoom activity a bit more interesting

made dynamic marker activity a bit more interesting
