Max Krasnyansky 2b129ccfa0 hexagon: support for backend sampler (#29502 )

* hex-topk: trying to improve/cleanup the pipeline

* hex-sampling: add STEP op

* hex-sampler: add SUM op

* hex-sampler: update CPY to support sampling cases

* hex-binary: add support for chunking to handle large logits

* hex-argmax: super basic version of ARGMAX

* hex-binary: support for scalars in extended buffers

* hex-binary: fix wrong indexing for dim 1 broadcasts across dim 2 slices

* hex-argsort: fix missing header

* hex-sampler: cleanup dma usage in the sampler related ops, and binary

* hex-build: disable autovectorizer, it is better to use explicit hints for critical loops

* hex-binary: fix perf regression due to is_1d fallback

* hex-ops: update supported ops
