When a render pass is closed, render pass queries are paused.  The code
that pauses queries however is conditioned to the render pass being
open.  In ContextVk::syncState, when processing
gl::State::DIRTY_BIT_DRAW_FRAMEBUFFER_BINDING, `onRenderPassFinished()`
is called. Later on, when the render pass is actually finished, the
queries are not paused.

This change moves the logic to pause render pass queries to
onRenderPassFinished().
