Subject: Remove init-time GLES per-frame callback

The GLES renderer interface now allows the per-frame callback to be
registered after initialization. This change updates the emulator to
use the new interface. Since reading back completed frames is slow
(due to pipeline flush/stall), a future change will enable the
callback only while multitouch emulation is actually in use.
