Applies to all Windows because we currently don't have a way to check

The workaround in https://chromium-review.googlesource.com/430887
was intended only for NVIDIA.

Re-creating the test window causes new native display to be created every time.
Normally, re-using the same native display with different implementation
would release the old implementation.
When new display is created instead of re-using the old one,
old implementation is never released, leaking memory.

Use SystemInfo to check if any of GPUs is NVIDIA
and apply the workaround only then,
reducing the leak on other platforms.

ANGLE calls WindowSurfaceVk::nextSwapchainImage() to prepare for
the next frame, which allocates an image (and other resources,
like semaphore). However, it's possible for
egl::Display::destroySurface() to be called before the next
submitFrame(), which prevents the image from being returned back
to the swapchain.

This fix refactors swapImpl() to separate out the present work, which
can be called as part of destroy() to return the allocated resources.

Chrome now has a googletest version that supports _TEST_SUITE_ macros
instead of _TEST_CASE_, so this CL cleans up some of the outdated usage.
