Opening Mod io with invalid mods create errors

[Stan]

To reproduce

• Load some mods for A25
• Switch to A26 notice you get red mods in the mod selector
• open modio anyway

Fixed in r25881

To reproduce the following errors:

• Enable Sharpening/FXAA in the options.

• Go in the mod selector and disable all mods
• Save the config
• Quit (e.g. alt + F4)

Or run the game with only the mod mod.

$ binaries/system/pyrogenesis -mod="mod"

ERROR: CCacheLoader failed to find archived or source file for: "shaders/effects/cas.xml"
ERROR: Failed to load effect 'cas'
ERROR: CCacheLoader failed to find archived or source file for: "shaders/effects/fxaa.xml"
ERROR: Failed to load effect 'fxaa'

A possible solution is to move all those effects into the mod mod.

In 27629:

Move some engine required files to the mod mod.

Most of the shaders are explicitely interned by the engine except for the one called "Model" which is not required (you can have maps with just terrain for visualization)
The rng files are called by the engine to validate structure.
The game has two overrides for high quality and normal water to be "ocean" and "default" respectively
The minimap flare folder is hardcoded see #6795
The default material now calls the dummy shader instead of the model one when in modmod
Move the default skybox, it will be required by _default.xml
The terrain materials are moved as well, for completeness, although they are currently not referenced.

This commit does not include atlas needed files as it cannot run without the public mod anyway for now. It will be done in a separate commit when we have the ingame editor that will require _default.xml for instance.

This commit is also needed to generate the spir-v shaders in the correct mods, in order to be able to launch the game with mod mod only.
