This extension adds support for the subgroup rotate instruction defined in SPV_KHR_subgroup_rotate.

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceShaderSubgroupRotateFeaturesKHR

## New Enum Constants

- `VK_KHR_SHADER_SUBGROUP_ROTATE_EXTENSION_NAME`

- `VK_KHR_SHADER_SUBGROUP_ROTATE_SPEC_VERSION`

- Extending VkStructureType:

  - VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SUBGROUP_ROTATE_FEATURES_KHR

- Extending VkSubgroupFeatureFlagBits:

  - VK_SUBGROUP_FEATURE_ROTATE_BIT_KHR

  - VK_SUBGROUP_FEATURE_ROTATE_CLUSTERED_BIT_KHR

## New SPIR-V Capabilities

- GroupNonUniformRotateKHR

## Promotion to Vulkan 1.4

Functionality in this extension is included in core Vulkan 1.4 with the KHR suffix omitted. The original type, enum, and command names are still available as aliases of the core functionality.
