posix_timers kself test failed in 6.12.y

Hi Thomas

Following posix_timers kself test failed in 6.12.y
-------------------------
not ok 7 check_sig_ign SIGEV_SIGNAL
not ok 9 check_rearm
not ok 10 check_delete
-------------------------

Reason of failure:
6.12.y does not support these KSELT tests,
Because the following commits were not backported in 6.12.y:
6017a158beb: "posix-timers: Embed sigqueue in struct k_itimer"
69f032c92cf: "signal: Provide ignored_posix_timers list"


is it feasible to backport in these commits or complete series of patch 
in 6.12.y ( [patch V7 00/21] posix-timers: Cure the SIG_IGN mess)
6017a158beb: "posix-timers: Embed sigqueue in struct k_itimer"
69f032c92cf8:  "signal: Provide ignored_posix_timers list"

if not, we shall revert following kself test from 6.12.y
45c4225c3dcc "selftests/timers/posix_timers: Add SIG_IGN test"
e65bb03e4427 "selftests/timers/posix_timers: Validate signal rules"


Thanks,
Alok
