imatrix : use GGUF to store importance matrices (#9400)
* imatrix : allow processing multiple chunks per batch
* perplexity : simplify filling the batch
* imatrix : fix segfault when using a single chunk per batch
* imatrix : use GGUF to store imatrix data
* imatrix : fix conversion problems
* imatrix : use FMA and sort tensor names
* py : add requirements for legacy imatrix convert script
* perplexity : revert changes
* py : include imatrix converter requirements in toplevel requirements
* imatrix : avoid using designated initializers in C++
* imatrix : remove unused n_entries
* imatrix : allow loading mis-ordered tensors
Sums and counts tensors no longer need to be consecutive.
* imatrix : more sanity checks when loading multiple imatrix files
* imatrix : use ggml_format_name instead of std::string concatenation

* quantize : use unused imatrix chunk_size with LLAMA_TRACE
* common : use GGUF for imatrix output by default
* imatrix : two-way conversion between old format and GGUF
* convert : remove imatrix to gguf python script
* imatrix : use the function name in more error messages
* imatrix : don't use FMA explicitly
This should make comparisons between the formats easier
because this matches the behavior of the previous version.
* imatrix : avoid returning from void function save_imatrix
* imatrix : support 3d tensors with MUL_MAT
* quantize : fix dataset name loading from gguf imatrix
* common : move string_remove_suffix from quantize and imatrix

* imatrix : add warning when legacy format is written
* imatrix : warn when writing partial data, to help guess dataset coverage
Also make the legacy format store partial data
by using neutral values for missing data.
This matches what is done at read-time for the new format,
and so should get the same quality in case the old format is still used.
* imatrix : avoid loading model to convert or combine imatrix
* imatrix : avoid using imatrix.dat in README

* Fix Gemma3n not executed as CUDA_GRAPH on NVGPUs
Gemma3n uses Matrix-Matrix addition as part of their input processing,
wrongly triggering CUDA_GRAPH disablement on NVGPUs even when batch-size
of 1 is used.
* Exclude `project_per_layer_input` by matching node names
This ensures that all other graphs which don't exhibit this pattern do
not have their behavior changed.
* Revert unnecessary formatting changes
