This removes the following for both Buffer and Texture: - The builder's SetInitialUsage - The object's FreezeUsage and TransitionUsage methods - The CommandBuffer Transition<Object>Usage methods All samples and tests are simplified as a result. This also obsoletes the UsageValidationTest which is removed. Some validation was dependent on "current usage" and hasn't been reintroduced for implicit transitions yet: - Buffers can be used while mapped - Swapchain textures can be used after they have been presented. Validation for these will involve collecting all the resources used by a command buffer and will be done in a follow-up patch.
