feat(wm): make active border with configurable

This commit introduces a new command which lets the user set a custom
width value for the active window border when it is enabled.

Unfortunately a little more width is required when working with rounded
windows on Windows 11 to fill the gap left by the rounding. The default
width remains set at 20.
