1. Add a new API -- sbgemv to support bfloat16 based gemv
2. Implement a generic kernel for sbgemv
3. Implement an avx512-bf16 based kernel for sbgemv

1. Added bfloat16 based dot as new API: shdot
2. Implemented generic kernel and cooperlake-specific (AVX512-BF16) kernel for shdot
3. Added 4 conversion APIs for bfloat16 data type <=> single/double: shstobf16 shdtobf16 sbf16tos dbf16tod
shstobf16 -- convert single float array to bfloat16 array
shdtobf16 -- convert double float array to bfloat16 array
sbf16tos -- convert bfloat16 array to single float array
dbf16tod -- convert bfloat16 array to double float array
4. Implemented generic kernels for all 4 conversion APIs, and cooperlake-specific kernel for shstobf16 and shdtobf16
5. Update level1 thread facilitate functions and macros to support multi-threading for these new APIs
6. Fix Cooperlake platform detection/specify issue when under dynamic-arch building
7. Change the typedef of bfloat16 from unsigned short to more strict uint16_t

Netlib style:
enum CBLAS_XYZ {X=1, Y=2, Z=3};
Intel MKL style:
typedef enum {X=1, Y=2, Z=3} CBLAS_XYZ;
With this hybrid style, code written in the latter form won't need any
modifications to be built with OpenBLAS. This change should not affect existing
code, although a warning may be emitted for C code which does the following
(does not occur with C++):
typedef enum CBLAS_XYZ CBLAS_XYZ;
warning: redefinition of typedef 'CBLAS_XYZ' [-pedantic]
