LPGEMM bench enhancements

Details:
- Moved the downscale & postop options from commmandline to
  input file.
- Now the format of the input file is as follows:
  dt_in dt_out stor transa transb op_a op_b m n k lda ldb ldc postops
- In case of no-postops, 'none' has to be passed in the place of
  postops.
- Removed duplication of mat_mul_bench_main function for bf16 APIs.
- Added a function called print_matrix for each datatype which can
  help in printing matrices while debugging.
- Added printing of ref, computed and diff values while reporting
  failure.
- Added new functions for memory allocation and freeing. Different
  types of memory allocation is chosen based on mode bench is
  running(performance or accuracy mode).
