Initial work for consolidation of ChibiOS platform files (#8327)

* Initial work for consolidation of board files and default ChibiOS configs.

* Migrate F401/F411 black pills for testing.

* Add early init bootloader jump flag.

* Add support for I2C in order to use i2c_scanner keymap.

* Add F401/F411 HSE bypass to get things booting.

* Exempt "hooked" ChibiOS conf files from updater script.

* Fix up ordering for bootloader_defs file check.

* Match previous $(KEYBOARD_PATHS) value for Proton-C, updated for all board configs.
