This PR/commit implements dense MXFP4 support (all tensors), and MoE NVFP4 (similar to MXFP4). It implements the quantization routine for all of these types.

This PR/commit implements dense MXFP4 support (all tensors), and MoE NVFP4 (similar to MXFP4). It also implements the quantization routine for these types:
Overview
See above.
More specifically, it also adds
NVFP4_MOEandMXFP4quantization types which are new. The engine could already process these but with warnings, and this also is fixed.Additional information
I found NVFP4 on my hardware to be decently fast. I'm using an i3 14100 with OpenBLAS on musl libc, with 8 GB DDR5.
Unlike other implementations of finished MXFP4 and NVFP4 support, this gives the best of all the worlds. People who want a dense MXFP4 get it, people who want MoE NVFP4 get it, and now people can have NVFP4 too. This PR kills multiple birds with one stone.
