Support multi-button presses on Philips remotes

[fholzer]

Proposed change

ButtonPressQueue currently resets when receiving a button press from a different button than the previously received one. This prevents proper handling when pressing multiple buttons at the same time.

Additional information

Fixes #3591

This is still a draft. Would like to add another test to make sure multiple button presses are handled correctly. So far tests only check for multi-presses of the same button. Also want to wait for feedback from ericu65 in #3391

Manual tested fix from PR and on RDM001 simultaneous presses of both switches while in mode 2 (dual rocker) both events are received correctly now.
