[1.21.1] Modification of certain functions to improve Cyclic development

[Fred-Redstone-2]

Additions:

• New Consumer-based function for setItemStackNBTVal in TagDataUtil; now supports int, String and double values to be added to the tags

Modifications:

• Default vertex format in FakeBlockRenderTypes, to prevent the game from crashing when calling these methods; the implementation does not take into account a texture or lighting map, so the vertex format should reflect it.
• Use of LevelRenderer instead of manually adding vertexes to a Consumer; allows for a better anti-aliasing on the block outlines drawn
