Tidy creation of TBS peripheral firmwares

[peterbarker]

Incorporates https://github.com/ArduPilot/ardupilot/pull/30381 (fix for hex file generation when using USE_BOOTLOADER_FROM_BOARD)

The hwdefs were referencing a board which didn't exist (via USE_BOOTLOADER_FROM_BOARD); fixed to point to correct base board

Fixed creation of .hex files with embedded bootloader where USE_BOOTLOADER_FROM_BOARD with a patch to chibios_hwdef.py and waf's chibios.py

Rebuilt the base bootloader under correct name.

Removed old bootloader files and their -bl.dat files

with_bl.hex files created (eg.):

Only output change is that the romfs on the periphs is 60-odd bytes larger.
