Keypad Library: allow for arrays for pull and value_when_pressed

[s-light]

split from #7919 (comment)

allow for arrays for pull and value_when_pressed -
so we can use the same object for all three buttons -
i came across this need for the Adafruit ESP32-S3 Reverse TFT Feather
as on these Button D0 is opposite to D1 & D2 for the sake of deep-sleep wake-up..

this is found on the following boards:

• Adafruit ESP32-S2 Reverse TFT Feather pinout - button description
• Adafruit ESP32-S3 Reverse TFT Feather pinout - button description

maybe there are other boards with similar setups...

This might help: I wrote a library to mix multiple keypad scanner instances (or compatible) into a single event queue, with this example for using it with the reverse TFT feather:
