transaction: don't reconfigure X views unless integral coords changed
Sway logical coordinates are doubles, but they get truncated to integers when sent to Xwayland through `xcb_configure_window`. X11 apps will not respond to duplicate configure requests (from their truncated point of view) and cause transactions to time out. Fixes #5035.
