hexagon refactor all Ops to use local context struct (#19819)
- hexagon: refactor set/get/sum-rows ops to use local context
- hexagon: refactor ROPE and Softmax Ops to use local context
Improves performance a bit by precomputing things and saving in the context.
- hexagon: refactor activation ops to use local context struct
- hexagon: refactor unary ops to use local context struct and DMA/VTCM
- hexagon: use aligned hvx_scale function
- hexagon: remove unused fields from op_context
- hexagon: rewrite ROPE to use DMA and VTCM scratchpad
- hex-rope: keep N rows in scratchpad (instead of just two)
- hex-rope: introduce rowidx cache
- hex-rope: remove unused fields
- hex-rope: rewrite dma prefetch logic to allow for multi-row fetch/compute
also removes the need for fastdiv.
- hex-rope: minor formatting
- hex-rope: use indices and unroll the loops
- hex-rope: more updates to cleanup rope-block handling
- hexagon: cleanup supported type/dims checks
- hexagon: all reduce funcs replicated across lanes
There is no need to explicitly replicate the first value.
- snapdragon: update adb and windows scripts to use ubatch-size 256
Updated Ops support handles larger ubatches.
