[sw, rom_ext_signer] Add temporary development files
- rom_ext_blank_image.bin: 1024 byte (slightly larger than the
manifest) binary initialised with zeros.
- system_state_value.bin: 32-byte dummy system state value initalised
with 0xA5.
- test_key_private.der: private key in DER format, converted from
`sw/device/rom_exts/keys/test_key_private.pem`.
- usage_constraints.bin: 256-bit dummy usage constraints binary blob
initialised to 0xA5.
NOTE: These files are for development, debug and tetsing purposes.
They are likely to be completely or partially removed as the
implementation matures.
