* 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.

* FA: provide work buffer for K repacking
* Add header to avoid comp0iler warnings

* Slightly better
* WIP (Zen4)

* 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

* 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

* Metal: WIP to update Metal FA implementation
Dk=192, Dv=128 works, but not Dk = 576, Dv = 512
* Metal FA: go to float
* WIP
* Metal FA: MLA options now all work

* MoE improvements on Metal
This version beats mainline, there are things I don't understand:
* Mianline has effectively gone to GEMV for MUL_MAT_ID. We can do the
same, but we are 30% slower. Why?
* Using actual GEMM, we beat mainline with ubtach size of 128. But then
performance degrades. Why?
* Some cleanup
* Much better
