Promotion to Vulkan 1.4

Functionality in this extension is included in core Vulkan 1.4, with the KHR suffix omitted. However, Vulkan 1.4 implementations only have to support local read for storage resources and single sampled color attachments.

Support for reading depth/stencil attachments and multi-sampled attachments are respectively gated behind the new boolean dynamicRenderingLocalReadDepthStencilAttachments and dynamicRenderingLocalReadMultisampledAttachments properties, as described in the Version 1.4 appendix.

The original type, enum, and command names are still available as aliases of the core functionality.
