…ipify-perl`, changed the hipification logic, tuned up the `hipify-perl` performance

+ [#1625] Added the `-miopen` option to `hipify-perl`
+ [IMP] The logic of hipification by both tools is changed and aligned:
  1. `-roc` implicitly sets on `-miopen`
  2. `-roc` + `-miopen` is the same as `-roc`
  3. `-miopen` means hipification `cuDNN` to `MIOpen`, the rest of `CUDA` APIs - to `ROCm HIP` APIs
  The third option is made to give users the ability to mix `MIOpen` with `HIP` instead of `ROC`
+ [IMP][#1776] As a side effect of the introduction `-miopen` in `hipify-perl`, its code generation was changed drastically, which led to:
  1. Decreasing of the generated code: 14% in lines of code, 10% in file size
  2. Performance improvement on hipification ~21%
+ [ToDo][#1625] Add the tests for combinations of `--roc`, `--miopen` options
+ [ToDo][#1776] Decrease the `hipify-perl` code more
+ [ToDo][#1776] Improve  the `hipify-perl` performance more
