Fix window resize with DPI change

When the DPI factor changed and the window hasn't been resized,
Alacritty incorrectly resized the window to the previous size without
scaling it by the new DPI factor.

This has been fixed by making sure that every resize event triggered by
a DPI change uses the DPI factor to scale the window.
