* 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.

* lora : fix llama conversion script with ROPE_FREQS
* convert : refactor rope_freqs generation
This should also fix vocab-only conversion for Phi-3.
* convert : adapt MiniCPM3 to separate rope_freqs insertion
MiniCPM3's tokenizer is treated as a SentencePiece tokenizer to avoid
having to run its custom Python code which mixes tokenization
in the same file as tool calls.
gguf-py : add long and short RoPE factors to tensor mappings
Empty, but the key names are used to populate the mappings.

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

* FA: provide work buffer for K repacking
* Add header to avoid comp0iler warnings
* WIP
* WIP
* WIP
* WIP
* Slightly better
* WIP (Zen4)
* WIP
* Try to improve for unusual number of heads/number of threads
* Use mul_mat_qX_0_q8_2_Tx for q6_0 in FA
* Use mul_mat_qX_0_q8_2_Tx for q4_0 in FA
* Use Sum4q4 for q4_0
* WIP
* WIP
* Much better FA TG with q8_0 KV cache
Just repack it even for TG. But do the repacking for k_step rows,
not the whole K tensor.

* Add GLM-4-0414 model support
Based on zRzRzRzRzRzRzR's PR on mainline llama.cpp.
Still some issues where it doesn't work:
* offloading >=60 layers to GPU
* no flash attention
* Remove seemingly unused llm_tensor enums
Both of these seem unused and LLM_TENSOR_ATTN_POST_NORM already
existed which seems pretty similar? Don't think they were used in the
python code either...
So removed these as possibly just cruft:
* LLM_TENSOR_POST_ATTN_NORM
* LLM_TENSOR_POST_MLP_NORM
* Set flash attention precision to f32 on GLM4 arch
* Set non flash attention precision to f32 on GLM4
* Remove reshape_3d() for Vcur in build_glm4()
This fixes the non-flash-attention inferencing on both CPU and CUDA.
* Slightly better CPU TG performance for GQA
* Better CPU FA implementation for TG when GQA
* Minor

* imatrix: collect layer influence statistics
* imatrix: collect layer influence statiscs also for the last layer
For the last layer we need to use the input for the output.weight
tensor. Last layer(s) tend(s) to be important, so it is useful to also
have its influence metric.
* imatrix: separate metric for attention and ffn importance
* Use stripped tensor name, not src0->name
