Subject: feat(render): implementation-free api texture factory

Provides an implementation-free API Texture factory an builder.
Deprecates gregtech.api.objects.GT_*Texture.java classes

Once all GregTech add-on will be migrated to the new implemnetation-free API,
changes to the implementation will not affect the add-on.

For now, this API allow rendering of in-world glow textures.
In-inventory/hand rendering of glow texture require implementation changes
that are postponed until no add-on uses the deprecated embedded implementation API.
