Switch to Zephyr USB + QoL changes

• Enable full builds
• Two additional NXP boards

Thanks!

Re the autogen_board_info.toml files: if we wanted to turn on/off a module for a whole class of boards, would we need to re-do the builds locally for all those boards and recommit? Maybe using cascading toml to provide defaults would make sense in the long run so this extra step doesn't need to be done, like the cascading that mpconfig/mpconfigport/mpconfigboard provide.

Ya, it is kind of annoying but I added a make all (and make clean-all) to do it in one pass. This info is used in the doc build. These files are essentially a cache so that we don't need to clone all of zephyr, compute the dts and then run some of our Python to determine which modules are enabled.
