Implement the handle-based create, queue, priority, cancellation, and teardown APIs for CONFIG_LIBC_USRWORK. Custom queues use configurable pthread worker pools while the predefined USRWORK queue remains available. Match scheduler-backend delay, replacement, cancellation, and lifecycle semantics. Restrict the libc backend to task context because it uses blocking synchronization. Tested on an STM32H7 PX4 FMUv6C with ostest wqueue in Protected user space.

User-space work queues provide deferred processing in protected and
|
|
kernel builds. Dynamically allocated user-mode work queues require
|
|
pthread support. The predefined protected-build USRWORK queue does
|
|
not require pthread support.
