Arduino: ESP32-S2 USB modes

I picked up some new ESP32-S2 boards to play around with. These newer boards come with native USB on board, instead of a separate USB to serial chip to handle communications. With this new chip, there are some new USB acronyms in the Arduino menus. I kept getting them confused so I looked them all up and am committing them here for future reference.

Mode Explanation
USB DFU Device Firmware Upgrade: Upload mode
USB CDC Communication and Data Control: UART/Serial mode
USB MSC Mass storage device class
USB HID Human Interface Device: Mouse/Keyboard emulation
