GPU Vulkan: handle VK_ERROR_SURFACE_LOST_KHR in acquire path

Browse Source 
On Android, backgrounding and foregrounding an app causes the Vulkan
surface to be destroyed. vkAcquireNextImageKHR returns
VK_ERROR_SURFACE_LOST_KHR, but the acquire while(true) loop only calls
RecreateSwapchain which doesn't recreate the surface, resulting in an
infinite retry loop and a black screen.

Handle VK_ERROR_SURFACE_LOST_KHR by setting both needsSurfaceRecreate
and needsSwapchainRecreate, then returning to let the existing
recreation path handle it on the next call.

Fixes #15322
