Add debounce support to MomentaryButton class

[RichardPar]

Problem - One button press on an external tact-switch resulted in a very erratic menu navigation. Using a Heltec Wireless paper, but should be applicable for all momentary button presses.

• Updated constructors to include debounce_ms parameter with default value.
• Implemented debounce logic in the check method to improve button press reliability.
• Added setDebounceMs and getDebounceMs methods for debounce configuration.
