Expose View.executeHardwareAction()

Bug #10911502

Views creating hardware resources need a way to safely interact
with the hardware. This new method invokes HardwareRenderer.safelyRun()
which executes a Runnable after making sure the hardawre rendering
context is in a valid state.

With the OpenGL backend, executeHardwareAction() tries to call
eglMakeCurrent() if needed. This method is not guaranteed to
work.
