Change sampledImageIntegerSampleCounts to sampleCounts

The logic of PhysicalDevice::getImageFormatProperties(), as well as
testing with ANGLE, shows that multisampling of integer formats is
supported and works.  The value of
VkPhysicalDeviceLimits::sampledImageIntegerSampleCounts should therefore
be set to:

    VK_SAMPLE_COUNT_1_BIT | VK_SAMPLE_COUNT_4_BIT
