Subject: [PATCH] winit: Fix preferred window size not being taken into account
 when it changes multiple times between window creation and the resize event
 received from the window manager

In this phase between the window being resized and receiving the resize event, the pending_requested_size variable tracks the value to be used in adjust_window_size_to_satisfy_constraints. Unfortunately,
it was never set.

Amends commit 1c73144b09d263ebe20cf5e7cf500e7d4d5ac3b5.

Fixes #8452
