- Compute row size for the temp buffer based on the output of the first pass. - Update shader addressing math to use the output row size - Pass the output row size as "ncols_output", what used to be "ncols_output" is now "k" For the common case of K=40 and src0=(200000,1,1,1), this reduces the temporary buffer from about 3.2MB to 500KB.

Changed the test names from debian to ubuntu as it is more stable than Debian Trixie 2.

Previously, cmake was forcing `_WIN32_WINNT=0x0A00` for MinGW builds, This caused "macro redefined" warnings with toolchains that define the version. This also removes the `GGML_WIN_VER` variable as it is no longer needed. Signed-off-by: Adrien Gallouët <angt@huggingface.co>

This PR adds ZenDNN backend support for accelerated inference on AMD EPYC™ CPUs.
Background
ZenDNN is AMD's optimized deep learning library for EPYC processors, providing high-performance primitives for inference workloads. It uses the LowOHA (Low Overhead High-performance) MatMul operator for efficient matrix multiplication.
Changes
