GPIO-based Input mode and profile select on boot

[rmaccrimm]

This PR implements a couple of related features I've been working on:

1. Use GPIO pins for boot input mode select #1425
2. Option to select a profile to load along with the input mode

My goal with the second was to be able to set per-console profiles but not require a hotkey to be set to use them (to reduce the risk of accidentally triggering the hotkey mid-game).

This is accomplished with new configuration separate from the existing boot input-mode mapping, called BootModeOptions. It includes a flag to enable/disable the functionality and I've done my best to maintain the old behaviour when it's disabled. The web-config looks like this (it's an entirely new page as that was just easier, largely based off the pin mapping page):

Some other non-functional changes I made:

• Reworked the BootAction type to try to reduce the number of switch statements to update
• move the INPUT_MODES object from SettingsPage.jsx to a new file so it would be easier to re-use on a new page
• changed what appears to be a random typo I came across (REVERSE_UP_DEFUALT)
