Unsure of the history of the ESP32_S2_WROVER board (and why it wasn't
named GENERIC_S2_...) but now it's a variant of the generic S2 board.
Also removes the non-existent CONFIG_USB_AND_UART from all S2 boards.

This commit re-enables the command-line make option "FROZEN_MANIFEST". The
boards/*/mpconfigboard.cmake will now use the command-line FROZEN_MANIFEST
value if supplied.
Usage: make FROZEN_MANIFEST=~/foo/my-manifest.py
