  Vulkan: Add avoidInvisibleWindowSwapchainRecreate feature
  
  There is a bug on some NVIDIA drivers on Linux X11 when
  `vkAcquireNextImageKHR()` constantly returns `VK_ERROR_OUT_OF_DATE_KHR`
  if recreate the swapchain while window is not visible.
  
  If not recreate the swapchain after window resize - nothing happens,
  acquire and present works without errors. But if recreate the swpahchain
  to the `VkSurfaceCapabilitiesKHR::currentExtent` the next
  `vkAcquireNextImageKHR()` will return `VK_ERROR_OUT_OF_DATE_KHR`. ANGLE
  will retry to recreate the swapchain one more time and fail the call.
  
  Enabling the "avoidInvisibleWindowSwapchainRecreate" feature will avoid
  swapchain recreation when window size changes while it is not visible.
  
  Test: angle_end2end_tests --gtest_filter=EGLSurfaceTest.ResizeInvisibleWindow/*
