Multiple changes to multiple PDKs:
1) Fixed the gf180mcu_fd_io GDS.  Previously the GDS was being
   updated with a modification after building the magic
   database files with GDS file pointers, rendering the file
   pointers incorrect.  The script has been moved to a filter
   so that it occurs before the magic database files are
   generated.
2) The gf180mcu device generator script updated mainly to remove
   the drain-extended and asymmetric devices from the device menu,
   since the drawing routines are unfinished (work in progress).
3) The sky130 tech file updated to add the extended drain layer,
   along with GDS generation rules and DRC rules.  The device
   generator for the extended drain devices is still a work in
   progress.
4) The gf180mcu "torture test" script corrected for device names
   and updated with additional devices.
5) The xschemrc file for gf180mcu updated to add the PDK path
   corresponding to the open_pdks installation location.
