fw/testfw: Use fw_ram for firmware stack
This means firmware's stack shouldn't be accessible to programs
running in app_mode.

It also means we don't need to take special care of secure_ctx which
can now be an ordinary stack variable.

Nonetheless we zero out secure_ctx after final use and inline some
assembler to zero out the entire fw_ram after use, just before
switching to app_mode.

- We always assert on allowed commands in a state.
- We don't allow FW_CMD_LOAD_APP to be used twice.
- Enter fail state on read buffer overrun, header endpoint not for us,
  header parse error, and unknown firmware command.

fw: Use byte readable UDS
UDS is now byte readable (but not writable).

Use UDS and USS directly in a blake2s_update() instead of
concatenating them into fw_ram. UDS will still live for a short while
in fw_ram in the blake2s context buffer but will soon be overwritten.
