Fix Wayland window_can_set_mode ExclusiveFullScreen

[TCROC]

I'm currently testing out all of our supported platforms for the game we are getting ready to release. I noticed that ExclusiveFullScreen didn't work on Wayland. I dug in, fixed it, then found this PR beat me to it: #100898

But it appears the PR missed the window_can_set_mode method so here I am updating that as well. Let me know if you would like me to change anything :)

If possible, I suggest adding a before and after screenshot or some other information on how this was tested. You can also show what the other PR missed by forgetting to adjust window_can_set_mode().

Tbh, I just set everything that supports FullScreen to also support ExclusiveFullScreen. I noticed the other pr missed a case statement in this method. I am not sure if it has any visual effect. Maybe someone with more knowledge knows how this method is used internally? I presume it comes into effect at some point. Even if not, I suspect it should still return true for the sake of correctness since the other pr went through and now Wayland does indeed support ExclusiveFullScreen by performing the same behavior as FullScreen.

Shouldn't make any difference, since window_can_set_mode seems to be only called for minimized and maximized modes.

But all other platforms and other Wayland code fall back from EXFS to regular FS, so it makes sense.

Ye this is an internal method and nothing currently uses that branch (for now) so this is more of a correctness change, which I do approve! :DDDD

Thanks!
