* 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

* iq3_k: slightly better quantization
Not much of a difference for most models, but this change
avoids what it looks like a catastrophic failure for DeepSeek-Lite
(PPL is now 7.041 vs 7.314 on main).
* Small improvement for type-1 quants

* Make sure no interleaved quants are being used for token embeddings
also with `--pure` and/or `--custom-q`.
* Simplify

* Better make_qx_quants
Tested with q4_0 and q3_K (pure, imatrix), and the improvement is
quite significant.
* Sae for iq4_nl, iq4_xs

* WIP - not working
* q8_0 without bells and wistles works
* It works for q8_0
* Use bf16 instead of f16,int16
* q4_0_r8
* q5_0_r4
* q6_0_r4
* Also q4_1 and q5_1
* Add check if selected type is possible with --pure
I often want to quantize with --pure to see quantization performance
without quantization mixes. But for models where there qre tensors
with row sizes that are not multiple of 256, this results in a crash
for k- and i-quants. Hence, lets add a check if the quant selected
via --pure is applicable, and change it if not.

* Make fused MoE reproducible
As a bonus, peak performance at pp2048 with u_batch = 2048 is
~8% better.
* Slightly better
* Also do it for non-fused mul_mat_id

* Improve DeepSeek batched processing speed
* Revert the commented out section in iqk_mul_mat.cpp
It does have some benefit at long contexts.

* WIP Gemma3: not working
* gemma3: build_gemma3 seems to be working now
* Revert changes to convert_hf_to_gguf.py
It wasn't working, so I guess, it is better to leave the
conversion up tp upstream.
