[DO NOT REVIEW] mock-array: report error if all pins are not in .vcd for read_vcd

[oharboe]

ces_0_0/io_lsbIns_1 exists in this .vcd file, but it doesn't have any activities set from vcd. The signal is 0 throughout the run.

To reproduce with sta only, untar and run mock-array-read-vcd.tar.gz

The tar file was made from this PR and:

make DESIGN_CONFIG=designs/asap7/mock-array/config.mk final simulate power

Output:
