- 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
When there are multiple NUMA nodes and hyper-threading causes adjacent logical cores to share a physical core (e.g., common -> avail[i] = 0x5555555555555555UL), the numa_mapping function should not use a bitmask for filtering, as this would lead to redundant masking with the subsequent local_cpu_map function.
Added HFLOAT16 support for RISCV64
Added shgemm_kernel_8x8 for RISCV64_ZVL128B and shgemm_kernel_16x8 for RISCV64_ZVL256B based on HFLOAT16
The instruction sets used are ZVFH and ZFH, which need to be supported by RVV1.0

Using `OpenMP::OpenMP_LANG` targets for CMake is less error-prone than
passing the compiler and linker flags manually. Furthermore, it allows
the user to customize those flags by setting `OpenMP_LANG_FLAGS`,
`OpenMP_LANG_LIB_NAMES`, and `OpenMP_omp_LIBRARY`.
The warning was:
```

```
The added define is the same as is already present in the TLS part of
`memory.c`. This follows up on gh-4681.
The warning was:

The use of `volatile` for `newmemstruct` seems on purpose, and there are
more such constructs in this file. The warning appeared after gh-4451
and is correct. The `free` prototype doesn't expect a volatile pointer,
hence this change adds a cast to silence the warning.
Use microarchitecture name instead of meaningless strings to name the core,
the legacy core is still retained.
1. Rename LOONGSONGENERIC to LA64_GENERIC
2. Rename LOONGSON3R5 to LA464
3. Rename LOONGSON2K1000 to LA264
