vulkan: Remove transfer_ctx, do everything in compute_ctx. (#18945)
* vulkan: Remove transfer_ctx, do everything in compute_ctx.
We had a bug where a set_tensor_async (using transfer_ctx) didn't get
submitted before the graph_compute (using compute_ctx) that came after
it. To avoid this sort of issue, just do everything in compute_ctx.
Remove transfer_cmd_pool, which was already unused.

vulkan: Use mul_mat_vec_id for small values of n (#18918)
Change ggml_vk_mul_mat_vec_id_q_f16 to loop over the batch dimension and
update the indexing calculations in get_offsets.
Mat-vec is faster than mat-mat for small values of n. We don't get the same
reuse of the weights as in the non-ID path, but with this the cost is linear
in n rather than n>1 being far slower than n==1.

model-conversion : add BUILD_DIR variable to run-converted-model scripts (#18927)
This commit adds a BUILD_DIR variable to the scripts used for running

The motivation for this is that currently the `build` directory is
hardcoded and it can be useful to specify a different build directory,
with builds for different configurations.

hexagon: support for OP_CPY, host buffers now optional, hvx-utils refactoring and optimizations (#18822)
* hexagon: disable repack buffers if host buffers are disabled, improved handling of env vars
* hexagon: add support for OP_CPY fp16/fp32 -> fp16/fp32
Factore out all hvx_copy functions into hvx-copy.h header and reduced code duplication.
Update HTP ops infra to support OP_CPY
* hexagon: cleanup and refactor hex/hvx/htp headers and helper libs
hex is basically all scalar/core platform stuff (L2, DMA, basic utils)
hvx is all hvx related utils, helpers, etc
htp is higher level stuff like Ops, etc
hvx-utils library got a nice round of cleanup and refactoring to reduce duplication
use hvx_vec_store_a where possible
* hexagon: refactor HVX sigmoid functions to hvx-sigmoid.h
Moved sigmoid and tanh vector functions from hvx-utils.h to a new header
hvx-sigmoid.h. Implemented aligned and unaligned variants for sigmoid
array processing using a macro pattern similar to hvx-copy.h. Updated
act-ops.c to use the new aligned variant hvx_sigmoid_f32_aa. Removed
unused hvx-sigmoid.c.
* hexagon: factor out hvx-sqrt.h
* hexagon: mintor update to hvx-utils.h
* hexagon: remove spurios log
* hexagon: factor out and optimize hvx_add/sub/mul

* hexagon: refactor reduction functions to hvx-reduce.h
Moved `hvx_self_max_f32` and `hvx_self_sum_f32` from `hvx-utils.h`/`.c` to `hvx-reduce.h`.
Renamed them to `hvx_reduce_max_f32` and `hvx_reduce_sum_f32`.
Added aligned (`_a`) and unaligned (`_u`) variants and used macros to unify logic.
Updated `softmax-ops.c` to use the new functions.
* hexagon: refactor the rest of arithmetic functions to hvx-arith.h
Moved `hvx_sum_of_squares_f32`, `hvx_min_scalar_f32`, and `hvx_clamp_scalar_f32` from `hvx-utils.c/h` to `hvx-arith.h`. Implemented aligned/unaligned variants (`_aa`, `_au`, etc.) and used macros to reduce code duplication. Updated `hvx_min_scalar_f32` and `hvx_clamp_scalar_f32` to use `dst, src, ..., n` argument order. Updated call sites in `act-ops.c`.

Updated these functions to use `dst, src, ..., n` argument order and updated call sites in `act-ops.c`. `hvx_sum_of_squares_f32` remains in `hvx-utils.c` as requested.

- Modify `hvx_sum_of_squares_f32` in `ggml/src/ggml-hexagon/htp/hvx-reduce.h` to use `dst, src` signature.
- Implement `_a` (aligned) and `_u` (unaligned) variants for `hvx_sum_of_squares_f32`.
- Update `hvx_reduce_loop_body` macro to support both returning and storing results via `finalize_op`.
- Update existing reduction functions in `hvx-reduce.h` to use the updated macro.
- Update `rms_norm_htp_f32` in `ggml/src/ggml-hexagon/htp/unary-ops.c` to match the new signature.
