Currently we query the backbuffer's age in RenderCompositorEGL::BeginFrame(). This makes the driver dequeue a backbuffer, which may cause the driver to block until a buffer is available. (See bug 1668878.) We should delay calling this until necessary (in Renderer::composite_simple()) to increase the chances that the backbuffer is available.

Currently we query the backbuffer age in
RenderCompositor::BeginFrame(). Querying the age on android requires
the driver to dequeue a new backbuffer. By doing this right at the
start of the frame, we may cause the driver to block until a buffer is
ready.
We don't actually need the buffer age until part way through
rendering, in Renderer::composite_simple(), by which point there is a
bette chance the buffer is availible. So move the query to there instead.
