headers: Update to Vulkan header version 1.1.87

Updated:
- include/vulkan/vulkan.h
- include/vulkan/vulkan.hpp
- include/vulkan/vulkan_core.h
- registry/genvk.py
- registry/reg.py
- registry/validusage.json
- registry/vk.xml

Added:
- include/vulkan/vulkan_fuchsia.h

Note: A local, modified version of Vulkan-Docs/xml/reg.py was used to
generate these files. This modification filters out disabled extensions
when populating the structextends list for a given base struct.
