samples: tests: bluetooth: Add support for frdm_rw612

Adding bt_tester support.

Adding bt_tester app build
with Twister for frdm_rw612 board

Fix failing tests/samples due to unsufficent MPU ressources
by releasing unnecessary MPU regions.

Twister builds added on peripheral/central ht and
enabled Power manager on those examples to cover
the CI builds with PM enabled.
