libhwc2.1: move specific restriction function to ExynosMPPModule class

We may have specific restriction to prevent underrun in high refresh
rate situation. We should need to check this restriction when switching
refresh rate from low to hight to re-assign resources if needed.

Bug: 266850798
Test: play 4k video and switch refresh rate
