gdb: LoongArch: Add system call support for process record/replay

The process record and replay function also need record Linux
system call instruction. This patch adds LoongArch system call
number definitions in gdb/arch/loongarch-syscall.h, and adds
loongarch_linux_syscall_record() in gdb/loongarch-linux-tdep.c
to record system call execute log. With this patch, the main
functions of process record/replay and reverse debugging are
implemented.

The LoongArch system call numbers definitions are obtained from Linux kernel.
