vk: add logs and notes about mod/spr load sequence

ref/vk/NOTES.md

@@ -505,3 +505,42 @@ Questions:
 - Should it apply the first found rule that matches a given geometry and stop?
   Or should it apply updates to the material using all the rules that matched in their specified order? Doing the first rule and stopping is more readable and perofrmant, but also might be verbose in some cases.
 - Should we do "automatic" materials? I.e. if there's no manually specified material for a texture named `"<TEX>"`, then we try to load `"<TEX>_basecolor.ktx"`, `"<TEX>_normalmap.ktx"`, etc automatically.
