feat(config): update border opts, add deprecations

This commit includes backwards-compatible renames of
active_window_border_offset and active_window_border_width to
border_offset and border_width respectively.

Since the invisible window border adjustments were removed in #678, the
invisible window borders set by the OS can now also be adjusted via
border_offset and border_width, which is the primary reason for the
rename.

invisible_borders has been marked as deprecated and the previously
deprecated alt_focus_hack option has been removed.
