Fix violations of MISRA C:2012 Rule 10.4 (operand of unsigned and signed)
in cancellation point handling code.
Changed all CANCEL_FLAG_* macro definitions and their usage to use unsigned
literals (1u instead of 1) to ensure consistent unsigned arithmetic when
performing bitwise operations. This eliminates mixed signed/unsigned operand
violations in:
- CANCEL_FLAG_NONCANCELABLE
- CANCEL_FLAG_CANCEL_ASYNC
- CANCEL_FLAG_CANCEL_PENDING
The changes affect cancellation point entry/exit logic, cancellation state
management, and cancellation type handling across both kernel and libc
implementations.
