anr: add xwayland support

[vaxerski]

supersedes #9436

for some reason xwayland apps dont wanna reply, dk why for now, but 9436 doesnt work on my end anyways

worse than mine

fixed, I guess that's what I get for blindly trusting your X usage and not reading the spec.

💀 idk? #9436 works perfectly fine for me

[vaxerski]

it's completely off spec

[nnyyxxxx]

wrong

[vaxerski]

another mistake is that _NET_WM_PING is not required to be supported, the app reports whether it does. xeyes doesnt and under your MR it would always be marked as ANR

[vaxerski]

read up on X11 WM_PROTOCOLS spec here https://specifications.freedesktop.org/wm-spec/1.4/ar01s06.html

[nnyyxxxx]

not an issue with the implementation though, we are just pinging the application. if it doesnt respond it doesnt respond

[vaxerski]

if the app doesn't report supporting pings, we cannot mark it as always ANR because it might be responding, just not to your pings.
