[raster] Remove the jitter exception.

The jitter exception used to be applied when two neighboring pixels
were barely inside the outline. One the left one was turned on then,
which contradicts the OpenType specifications.  Intended to remove
glitches, it caused disappearing lines and was softened by adding an
exception to the exception (#54589).

* src/raster/ftraster.c (Vertical_Sweep_Span): Drop the jitter exception.
