docs: Update firmware docs and move memory map
...
Update firmware docs to reflect new state machine, the new stack in
FW_RAM, and new loading address for app. Remove superflous technical
details from the software description.
Move memory subsystem and memory map to system_description.md and
refer to it directly by subsection elsewhere.

- 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.

machine to the same names as in the rest of software.md.
Mention the Zmmul extension and what it means and possible workarounds
for people developing with clang < version 15.

the need to send both is documented. This is followed up with adjustment
in the host programs' Go code, to try to reinforce this. LoadApp() will

will be unexported.
