vulkan: fix data race in mul_mat_id shader (#19790)

* 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.
