Updated both sky130 and gf180mcu to take advantage of today's
update to magic (version 8.3.411) which introduces parameter limits
in device extraction records.  That lets magic extract the correct
device where there are unique device models corresponding to
specific parameter values or value ranges.  The previous way of
doing this (used for sky130) involved defining identifier marker
layers for each device model, but since the markers did not
correspond to any foundry GDS layers, they could not be imported
from GDS.  With this PDK update, magic will now extract the
correct model name for high-value poly resistors and bipolars.
The method was extended to the gf180mcu process for bipolars,
which were previously not extractable except by the "device primitive"
property (which also does not work through GDS export/re-import).
