Remove GetViewBoundsWithResizeLock.

Remove GetViewBoundsWithResizeLock.

Before delegated rendering, it was needed to throttle resizes beyond the
existing resize ack mechanism, because we could receive the frame after
the ViewHostMsg_UpdateRect with the ack.
With delegated rendering, we receive the frame before the ack (ack is
sent in RenderWidget::didCompleteSwapBuffers, which necessarily happens
after CompositorOutputSurface::SwapBuffers which sends the
ViewHostMsg_SwapCompositorFrame)

This then avoids RenderWidgetHostViewAura::GetViewBounds from changing
based on renderer state, which removes transient states (and related
test flakiness).

This depends on https://codereview.chromium.org/286053002/ because this
exposes test flakiness.
