Fix crash when more than two GPUs.

Crash happened because MVKPhysicalDevices created inline in MVKSmallVector<, 2>
using emplace_back(). Crash occurred when attempting to reallocate memory in
MVKSmallVector, and move inline MVKPhysicalDevice instances. Revert to tracking
MVKPhysicalDevice as pointers, which are easy to move after memory reallocation.

Review and optimize all uses of MVKSmallVector::emplace_back().
Set VkPhysicalDeviceLimits::maxSamplerLodBias to zero since it's unsupported.
Return error and use VK_POLYGON_MODE_LINE for unsupported VK_POLYGON_MODE_POINT.
