* iq5_ks: basics
* iq5_ks: quantize
* iq5_ks: CUDA dequantize works
* iq5_ks: dot product works on CUDA
* iq5_ks: MMQ works
* iq5_ks: Zen4
* iq5_ks: AVX2
But is is not quite right, just like iq4_k, iq5_k, iq6_k, iq4_ks.
All these need fixing on AVX2.

* New DeepSeek FlashMLA
Does not work because the RoPE portion is stored at the end
in our case, while in mainline it is stored at the beginning,
and the FA kernel assumes that.
* Rearrange MLA K cache so it first new CUDA FA implementation
* constexpr and minor changes

* cuda: Remove unnecessary device to host copy of row ids
We get 3-4% TG speed improvement for DeepSeek-Lite just from that.
* CPU: fix get_rows when SER is used
With smart experts reduction (SER), one potentially uses fewer
experts than specified by the model. This is accomplished by setting
the ID of the not seected tensors to -1. Most of the necessary
stuff was implemented when I added the SER option, but I forgot
to update get_rows() for not quantized tensors. As a result, we
get random garbage for the weights of the not-selected epxerts,
which leads to garbage output. This commit fixes it on the CPU.
I'm not quite sure yet why the GPU is not working.

* CUDA WIP: support for FlashMLA-3
* Much better
The issue was that I did not change the number of warps
used for 3D matrix multiplications (wk_b * kv_cache, MoE),
so we ended up using 4 warps for TG. By going to 1 warp
in these cases, we get a significant boost in TG performance
(tested with DeepSeek-Lite)
* Sadly, the previous commit was wrong
* Finalizing
* Also add these
* Minor
* Minor tweak

* WIP
* WIP: still getting illegal memory access
* CUDA: MMQ for iq4_ks now works
~25% faster than dequantize+cuBLAS, ~10% slower than Q4_0 MMQ.
