Remove EXPAND/STRINGIFY macros.

They are error-prone by putting anything into a string (e.g.
EXPAND(RECOVERY_API_VERSION) would become "RECOVER_API_VERSION" if we
forgot to pass -DRECOVERY_API_VERSION=3).

RECOVERY_API_VERSION is the only user (in bootable/recovery) that gets
stringified. Assign it to a typed var and sanity check the value.

Don't see other reference to the macros from device-specific recovery
directories (they can still define that locally if really needed).

Test: recovery_component_test
Test: Sideload an OTA on angler and marlin respectively.
