[syscalls] Disable various syscalls when kernel.enable-debugging-syscalls=false

This disables:
- zx_debug_send_command()
- zx_ktrace_read()
- zx_ktrace_control()
- zx_ktrace_write()
- zx_mtrace_control()

zx_debug_read() and zx_debug_write() from kernel/syscalls/debug.cc
aren't disabled in this CL as they're used by src/tests infrastructure,
so they'll need a more involved procedure.
