More Granular Buzzer Controls

[nakoeppen]

This PR vastly improves buzzer controls for devices like the RAK WisMesh Tag and the T1000-E. Initially implemented as #1437, this expands on that to allow for the previously used master buzzer disable boolean AND a disable-on-serial boolean, both packed into the preexisting buzzer_quiet integer variable. Currently, I kept it so that three button clicks will only toggle the master buzzer disable, meaning that the disable-on-serial functionality will rely solely on the client app side of things.

On the technical side of things, Bit 0 is the master disable and Bit 1 is the serial disable. This means that:

• If buzzer_quiet = 0 (00 in binary), the speaker will never be disabled
• If buzzer_quiet = 1 (01 in binary), the speaker will always be disabled
• If buzzer_quiet = 2 (10 in binary), the speaker will only be disabled when connected to serial
• If buzzer_quiet = 3 (11 in binary), the speaker will always be disabled, with the serial disable also enabled

I have a different toggle mechanism which I have implemented but left commented out for now within UITask.cpp in the ui-new folder. This helps with testing since the client app has not implemented this functionality yet (buzzer will briefly beep when buzzer_quiet is set to zero, which helps to determine which setting you are on). If the community prefers the commented out toggle method as a means to swap, I would be happy to build on that.

@liamcottle @oltaco, I appreciated your opinions on the inital PR I had. Please feel free to let me know if anything needs to be adjusted here to maximize user accessibility. Pretty new to contributing to this project (and frankly open-source projects overall), but I certainly hope to be able to contribute more! Otherwise, this was tested successfully using the aforementioned commented out method on my WisMesh Tag.
