ci : add GGML_NATIVE=OFF and GGML_BMI2=OFF to windows-blas

This commit adds the GGML_NATIVE=OFF and GGML_BMI2=OFF flags to the
Windows BLAS build.

The motivation for this is that currently the Windows BLAS build
uses the native CPU instructions and if target systems do not support
these instructions, the build will fail like the linked issue reports.

Resolves: ggml-org#3889
