BlackMark d6b3e85284 build: emit an Intel-HEX beside every loader image

avrdude programs Intel-HEX, not ELF, and the build produced only ELFs — so
flashing a loader to a real chip meant running objcopy by hand. add_hex_output()
hangs a POST_BUILD objcopy on each loader image: the three tsb tiers through
add_tsb_variant, pureboot, and the re-timed pureboot9. .eeprom is dropped, being
its own avrdude update.

It uses the toolchain file's CMAKE_OBJCOPY rather than a hardcoded path, so
every chip preset emits hex, not just the mega. pbapp keeps its ELF alone: the
update test converts it to a raw binary itself, and it is not a flashing target.
