settings: Add Xwayland byte-swapped clients

Browse Source 
Recent versions of Xwayland can allow or disallow X11 clients from
different endianess to connect.

Add a setting to configure this feature from mutter, who spawns
Xwayland.

<summary>Allow X11 clients with a different endianess to connect to Xwayland</summary>
<description>
Allow connections from clients with an endianess different to that
of Xwayland.
The X server byte-swapping code is a huge attack surface, much of
that code in Xwayland is prone to security issues.
The use-case of byte-swapped clients is very niche, and disabled by
default in Xwayland.
Enable this option to instruct Xwayland to accept connections from
X11 clients with a different endianess.
This option has no effect if Xwayland does not support the command
line option +byteswappedclients/-byteswappedclients to control that
setting.
Xwayland needs to be restarted for this setting to take effect.
