This change implements the ability to get and set the WiFi back-end,
by leveraging a new script created for that purpose.
The idea is to be able to use 'wpa_supplicant' (which is the default
back-end in NetworkManager upstream) when 'iwd' (the default in
SteamOS) does not work for some reason.
This change interacts with another feature of steamos-manager, which
is to set debug mode for WiFi. Handling debug mode complicates things
substantially because those methods write config for 'iwd' and restart
the daemons/systemd units, with many interdependencies.
Instead of trying to implement all at once and attempt feature-parity
between back-ends on this aspect from the start, as a first step the
operations are just declared incompatible. As a result, if
WifiDebugMode=on the back-end cannot be changed, and conversely the
WifiDebugMode cannot be turned on when the back-end is
'wpa_supplicant'.

This may be useful in cases where SetWifiDebugMode has failed to
check what the current state/setting is.
Though if SetWifiDebugMode has failed we may be in weird state
so logs of steamos-manager should be checked to see what failed.

Changed mode parameter from i32 to u32 as well.
Change from Result<bool, Box<dyn std::error::Error>> to
std::io::Result<bool>
Adjust the xml to add the new method.
Make all private api use Result<()> types so we can do error checking.

When wifi debug mode is started trace-cmd start is executed with
the given buffer_size parameter.
Later when wifi debug mode is stopped, trace-cmd stop is executed
as well as trace-cmd extract to write the data to a file on disk.
In this way the steam client (or any dbus users...) can decide how
long to run trace-cmd for.
Change to create_dir_all so we don't get errors if it exists.

Adds set_wifi_debug_mode to enable or disable wifi debug mode.
Parameters are
mode (0 for off, 1 for on for now, expandable in the
future if more modes are needed).
buffer_size: a size in kilobytes per cpu (so 16 on the deck)
for the ring buffer that debug messages will get written into.
For now just adds or removes a iwd debug mode override and restarts
iwd.
next will add some trace-cmd commands to write the debug messages
to a file on disk.

And this attempt works now. I guess this is adequate to release
as a throw away implementation to replace later with something better.
Also add strip="symbols" for release builds to get it down to a lean
3.2M size.
