sched/pthread: move pthread mutex from syscall to user-space

Browse source 
Move pthread mutex operations from kernel-space syscall
interface to user-space implementations
to reduce syscall overhead. Relocate mutex holder list
tracking from task control block (tcb) to
thread local storage (tls) to improve memory layout and
cache efficiency. Add helper macros for
conditional mutex implementations and update syscall
interface accordingly.
