Mcc add perf tests improve performance #3699
Added perf tests to mcc module.
Also these optimizations have been added:
- added `parallel_for_` to `performThreshold()`
- removed `toL`/`fromL` and added `dst` to avoid copy data
- added `parallel_for_` to `elementWise()` ("batch" optimization improves performance of Windows version, Linux without changes).
Configuration:
Ryzen 5950X, 2x16 GB 3000 MHz DDR4
OS: Windows 10, Ubuntu 20.04.5 LTS
Performance results in milliseconds:
| OS and alg version | process, ms | infer, ms |
| -------------------- | ----- | ------ |
| win_default | 63.09 | 457.57 |
| win_optimized_without_batch | 48.69 | 111.78 |
| win_optimized_batch | 48.42 | 47.28 |
| linux_default | 50.88 | 300.7 |
| linux_optimized_batch| 36.06 | 41.62 |
