vkGetRenderAreaGranularity implementation

There's no reason to have any limitation on granularity in SwiftShader, so the granularity is always 1 pixel. Passes all tests in: dEQP-VK.api.granularity Bug b/119620965 Change-Id: Ie2f09737c0054da1b6806b9572e515446a8b1263 Reviewed-on: https://swiftshader-review.googlesource.com/c/24890Tested-by: Alexis Hétu <sugoi@google.com> Reviewed-by: Nicolas Capens <nicolascapens@google.com>
