gnu: godot: Update to 4.5.

Godot 4.5 has some issues with system files taking precedence over ones
included in the "thirdparty" directory; see
<https://github.com/godotengine/godot/pull/111094> for discussion.  This was
further motivation to use the upstream default of enabling volk, unbundling
it, and dropping the vulkan-loader input.  The volk files are already patched
to correctly load libvulkan.

[source]: Add patch to unbundle libjpeg-turbo.  Update snippet to preserve
accesskit, grisu2, smaa, and remove volk.

phase unbundle-volk.
