x11: Do not check hover state on properties change (#15518)

apricotbucket28 created 

This fixes an issue where the window's hovered state would be incorrect,
causing the cursor not to update because it would think the window
wasn't hovered ([relevant
check](https://github.com/zed-industries/zed/blob/a03beeeb5bcce3fbb464a5d2a06a6ae47e8dda92/crates/gpui/src/window.rs#L3016-L3017)).

The code here doesn't really seem to make sense, since there's already
the `XinputEnter` and `XinputLeave` events that indicate mouse focus
state on the window. The properties change event wouldn't necessarily
indicate when mouse focus changes.

Thanks @Emc2356 for reporting this on the Discord and helping figure out
the issue!
 
Release Notes:

- Linux: Fixed the cursor sometimes not changing on X11
