Treat stroke symbols like other symbols (#7789)

* WIP Treat stroke symbols like other symbols

Refer to #7788 for background.  This WIP PR covers psxy and seems to work as explained.  Will do the same for psxyz.

* Same for psxyz

they share the same stroke symbols.

* Only override color it one has been set

* Update the docs for strokable symbols

* Add a constant for the default size to pen width factor

* Update gmt_constants.h

* Fix color assignment if -G or -C given

* Introduce new default MAP_STROKE_WIDTH

* Minor fixes

* Deal with resets after reading symbols from data file

* Fix some PS and scripts

* More PS updates

* Update images.dvc

* fix output name and 2 PS files

* Update psevents.dvc

* Fix inverted CPT

* Increase RMS threshold due to architectures

* typos
