Use current mouse button state instead of saved values.

Same as #92415, but for mouse buttons.

Gave a look, things look fine!

I think that the freelook fix bundled is more of a workaround (see #92455 (comment) ) but it will do for now.

I also researched a bit on the Wayland side and things aren't bad at all. There's a bit of a focus tracking bug in the Wayland thread (which I'll fix soon), but otherwise everything gets reported properly by the compositor even in between focus changes (rightly so, as there's no pointer query API on WL), so we're mostly set :D

It is, and it's not related to mouse button state. Freelook can be activated by keyboard as well, and it's only checking its internal state after it is activated (or release event is received), releasing it on focus out as well seems to be reasonable thing to do.

Needs rebase.
