tools/perf: Update tools's copy of mips syscall table

tldr; Just FYI, I'm carrying this on the perf tools tree.

Full explanation:

There used to be no copies, with tools/ code using kernel headers
directly. From time to time tools/perf/ broke due to legitimate kernel
hacking. At some point Linus complained about such direct usage. Then we
adopted the current model.

The way these headers are used in perf are not restricted to just
including them to compile something.

There are sometimes used in scripts that convert defines into string
tables, etc, so some change may break one of these scripts, or new MSRs
may use some different #define pattern, etc.

E.g.:

$ ls -1 tools/perf/trace/beauty/*.sh | head -5
tools/perf/trace/beauty/arch_errno_names.sh
tools/perf/trace/beauty/drm_ioctl.sh
tools/perf/trace/beauty/fadvise.sh
tools/perf/trace/beauty/fsconfig.sh
tools/perf/trace/beauty/fsmount.sh
$
$ tools/perf/trace/beauty/fadvise.sh
static const char *fadvise_advices[] = {
[0] = "NORMAL",
[1] = "RANDOM",
[2] = "SEQUENTIAL",
[3] = "WILLNEED",
[4] = "DONTNEED",
[5] = "NOREUSE",
};
$

The tools/perf/check-headers.sh script, part of the tools/ build
process, points out changes in the original files.

So its important not to touch the copies in tools/ when doing changes in
the original kernel headers, that will be done later, when
check-headers.sh inform about the change to the perf tools hackers.

syscalls: Cleanup references to sys_lookup_dcookie()

commit 'be65de6b03aa ("fs: Remove dcookies support")' removed the
syscall definition for lookup_dcookie. However, syscall tables still
point to the old sys_lookup_dcookie() definition. Update syscall tables
of all architectures to directly point to sys_ni_syscall() instead.

tools headers UAPI: Sync files changed by new fchmodat2 and map_shadow_stack syscalls with the kernel sources

To pick the changes in these csets:

c35559f94ebc3e3b ("x86/shstk: Introduce map_shadow_stack syscall")
78252deb023cf087 ("arch: Register fchmodat2, usually as syscall 452")

That add support for this new syscall in tools such as 'perf trace'.

For instance, this is now possible:

# perf trace -v -e fchmodat*,map_shadow_stack --max-events=4
Using CPUID AuthenticAMD-25-21-0
Reusing "openat" BPF sys_enter augmenter for "fchmodat"
event qualifier tracepoint filter: (common_pid != 3499340 && common_pid != 11259) && (id == 268 || id == 452 || id == 453)
^C#

And it'll work as with other syscalls, for instance openat:

# perf trace -e openat* --max-events=4
0.000 ( 0.015 ms): systemd-oomd/1150 openat(dfd: CWD, filename: "/proc/meminfo", flags: RDONLY|CLOEXEC) = 11
0.068 ( 0.019 ms): systemd-oomd/1150 openat(dfd: CWD, filename: "/sys/fs/cgroup/user.slice/user-1001.slice/user@1001.service/memory.pressure", flags: RDONLY|CLOEXEC) = 11
0.119 ( 0.008 ms): systemd-oomd/1150 openat(dfd: CWD, filename: "/sys/fs/cgroup/user.slice/user-1001.slice/user@1001.service/memory.current", flags: RDONLY|CLOEXEC) = 11

#

That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.

tools headers UAPI: Sync files changed by the quotactl_path unwiring

To pick the changes in this csets:

5b9fedb31e476693 ("quota: Disable quotactl_path syscall")

That silences these perf build warnings:

tools headers UAPI: Sync files changed by landlock, quotactl_path and mount_settattr new syscalls

To pick the changes in these csets:

a49f4f81cb48925e ("arch: Wire up Landlock syscalls")
2a1867219c7b27f9 ("fs: add mount_setattr()")
fa8b90070a80bb1a ("quota: wire up quotactl_path")

That silences these perf build warnings and add support for those new
syscalls in tools such as 'perf trace'.

For instance, this is now possible:

# ~acme/bin/perf trace -v -e landlock*
event qualifier tracepoint filter: (common_pid != 129365 && common_pid != 3502) && (id == 444 || id == 445 || id == 446)
^C#

That is tha filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.

$ grep landlock tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
444 common landlock_create_ruleset sys_landlock_create_ruleset
445 common landlock_add_rule sys_landlock_add_rule
446 common landlock_restrict_self sys_landlock_restrict_self
$

This addresses these perf build warnings:

perf tools: Generate mips syscalls_n64.c syscall table

Grab a copy of arch/mips/kernel/syscalls/syscall_n64.tbl and use it to
generate tools/perf/arch/mips/include/generated/asm/syscalls_n64.c file,
this is similar with commit 1b700c997500 ("perf tools: Build syscall
table .c header from kernel's syscall_64.tbl")
