cmd/link: make Pciter more idiomatic

Rename it to PCIter and convert it to use methods.

Set pcscale once, during construction, to make call sites clearer.

Change some ints to bools.

Use a simple iteration termination condition,
instead of the cap comparison from the c2go translation.

Instead of requiring a Pcdata, which requires one caller
to synthesize a fake Pcdata, just ask for a byte slice.

Passes toolstash-check.
