Fix libffi6 download in the Loongarch64_clang CI job (for now)

Declare the "small" complex DOT and AXPY kernels for RISCV-ZVL256B static in addition to inline

Add cross-compilation parameters for RISCV64 targets in CMake

Fixes for some gcc warnings

SME1 based direct kernel (with alpha and beta) for cblas_sgemm level 3

Add infrastructure for BGEMV

Add CI support for building and validating OpenBLAS on WoA

Update cross-compilation instructions for the Android NDK

- Sets up all the various entrypoints for `bgemv`
- Adds `bscal` for use in the `bgemv` interface
- Adds test cases for comparing `sgemv` and `bgemv`
- Adds generic kernels for `bgemv_n` and `bgemv_t` which are accurate
enough to pass above tests

Add ID data for Intel Lunar Lake ("Core Ultra 200V series")

Improve bgemm and sbgemm testing

- Fixes wrong return type for `is_close`
- Adds stricter compiler flags for test files so we don't see the above
issue again
- Re-uses test helper functions between compare_sgemm_sbgemm/bgemm.c

Fix compilation of the new bgemm test

Add optimized BGEMM kernel for NEOVERSEV1 target

This also improves the testing and generic kernel by re-using the BF16
conversion functions.
