deps: Update Vulkan dependencies and remove fmt version constraint

- Update Vulkan-Headers to e43027a (1.4.306)
- Update Vulkan-Utility-Libraries to 8ec8482
- Update vcpkg to 2b8927f
- Remove version constraint for fmt package requirement
- Update VulkanHeaders version requirement to 1.4.306

This updates several external dependencies to their latest versions and
removes the specific version requirement for fmt while maintaining the
REQUIRED flag. The Vulkan-Headers version requirement is updated to match
the new submodule version.
