Summary
This PR adds sched_note_syscall_enter/leave hooks for the system call instrumentation.
Syscall wrapper library is created for the hooks.
(Moved from PR #1271)
Impact
If CONFIG_SCHED_INSTRUMENTATION_SYSCALL is enabled, new library libwraps.a is built and additional linker options are passed to the final link process.
All syscalls are hooked by sched_note_syscall_enter/leave,
At this moment, only Arm and RISC-V can enable it.
Testing
Tested by spresense:nsh and maix-bit:nsh by changing the following configurations.
CONFIG_DRIVER_NOTE=y
CONFIG_SCHED_INSTRUMENTATION=y
CONFIG_SCHED_INSTRUMENTATION_BUFFER=y
CONFIG_SCHED_INSTRUMENTATION_SYSCALL=y
CONFIG_SCHED_NOTE_GET=y
CONFIG_SYSTEM_NOTE=y
"note" command displays the system call information.
