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.

* gnu/packages/game-development.scm (godot): Update to 4.5.
[source]: Add patch to unbundle libjpeg-turbo.  Update snippet to preserve
accesskit, grisu2, smaa, and remove volk.
[arguments]<#:scons-flags>: Disable builtin libjpeg-turbo and sdl.
<#:phases>: In fix-dlopen-paths phase remove libudev and volk patching.  Add
phase unbundle-volk.
[inputs]: Add libjpeg-turbo-3, sdl3, and vulkan-volk.  Remove vulkan-loader.
* gnu/packages/patches/godot-libjpeg-turbo-unbundle.patch: New file.
* gnu/local.mk (dist_patch_DATA): Register it.
