egl: android: query native window default width and height (v2)

On android platform, the width and height of a native window surface may
be updated after initialization. It is therefore necessary to query android
framework for the current width and height.

v2: remove Android specific #ifdef's and just implement the fallback directly
if the platform query_surface() callback is not provided.
