Task list for VK_QCOM_rotated_copy_commands release

Adds an optional rotation transform to the copy commands `vkCmdBlitImage2KHR`, `vkCmdCopyImageToBuffer2KHR`, and `vkCmdCopyBufferToImage2KHR`, enabling rotated copies between resources where one resource contains rotated content and the other does not. Designed to complement `VK_QCOM_render_pass_transform` for pre-rotation workflows on mobile devices.

The task list for the VK_QCOM_rotated_copy_commands release is:

- [x] Vulkan Specification: https://docs.vulkan.org/refpages/latest/refpages/source/VK_QCOM_rotated_copy_commands.html
- [ ] Validation layer:

As each component is made public, the task will be checked off. When all tasks have been completed this issue will be closed and the extension will be fully released.

Review the VK_QCOM_rotated_copy_commands specification linked in the issue and the remaining validation-layer task. Determine whether a Vulkan-ValidationLayers PR has been made; the release is complete when validation-layer support is public and the unchecked task is marked complete.
