Changed functions to validate and return VK_ERROR_VALIDATION_FAILED_EXT when trying to allocate memory of size 0, create buffer with size 0, or image with one of the dimensions 0.

That's because vkCreateBuffer returns VK_SUCCESS for buffer with size = 0, so VMA then proceeded to allocation of size 0, which is a critical error, checked by an assert, but apparently some users don't enable asserts in VMA.

Added tests: function TestInvalidAllocations.
