MCUX usb ISR was making usb callbacks directly, which caused assertion
failures when a callback attempted to lock a mutex. Move USB callback
handler to separate thread, and make ISR notify thread via message
queue.
Fixes#40638

No sources were ever added to the `zephyr_library()` defined in
modules/hal_nxp/usb/CMakeLists.txt, thus removing this lib to avoid
the warning:
> No SOURCES given to Zephyr library: modules__hal_nxp__usb
>
> Excluding target from build.
