Should only send focus event when we actually will be sending anything related to the keyboard input.

Even if this particular keyboard event does not end in notifying the user of anything, my argument was that if I'm getting this X11 event here it is because this window has the focus. And if shared_state_lock.has_focus is false, then I should already have received it, so I'm sending it now to compensate for the missing one.

It should be done before mapping the window, or we could lose the firsst XInput2 events, such as the first FocusIn. Fixes rust-windowing#2841.

Hi! This seems to have stalled a bit. I think adding two unrelated "fixes" to the focus was a mistake. I'm rewriting the PR to just include the fix for #2841, that should be easier to merge. |

This PR fixes #2841.
Also it adds and extra commit that synthesizes a FocusIn event if ever the window receives a keyboard event while unfocused, that should not happen, but it does happen sometimes.
Feel free to comment on those two commits separately, if you prefer that.
