1. xtensa-build-zephyr.py: make --deployable-build the default …

   Every Linux developer should use deployable builds by default.
   
   Until Peter Ujfalusi's very recent work in this script, we had a
   complete `/lib/firmware/` structure disconnect between the IPC4 output
   of this script and the IPC4 expectations of the Linux kernel. To
   workaround this disconnect, every CI and Linux developer used to
   implement duplicate and inconsistent firmware deployment hacks.
   
   People crafting sof-bin releases also had to organize IPC4 releases
   manually, which was extremely error-prone and with limited test
   coverage (Thanks Kai and Mengdong!)
   
   Now that Peter gracefully fixed the layout, documented it in sof-docs
   and implemented it in this script, the time for all Linux developers to
   drop their inconsistent deployment hacks is overdue. All these hacks
   must be replaced with a simple, one-line recursive copy which makes sure
   the layout committed in version control is constantly tested by
   everyone.
   
   So, make deployable builds the new default.
   
   The new default will also help with sof-bin releases, making sure they
   use a well tested /lib/firmware/ layout.
   
   The --no-deployable-build was recently introduced to help minimize
   disruption and migration effort for people and automation who do NOT use
   Linux. The `/lib/firmware/` directory structure is irrelevant outside
   Linux (but everyone is of course free to choose it)
