Light-weight logging framewok for LPGEMM.

-A light-weight mechanism/framework to log input details and a
stringified version of the post-ops structure is added to LPGEMM.
Additionally the runtime of the API is also logged.
The logging framework logs to a file with filename following the format
aocl_gemm_log_<PID>_<TID>.txt.
-To enable this feature, the AOCL_LPGEMM_LOGGER_SUPPORT=1 macro needs to
be defined when compiling BLIS (with aocl_gemm addon enabled) by passing
CFLAGS="-DAOCL_LPGEMM_LOGGER_SUPPORT=1" to ./configure. Additionally
AOCL_ENABLE_LPGEMM_LOGGER=1 has to be exported in the environment during
LPGEMM runtime.
