cmd/compile: break apart dumptypestructs

dumptypestructs did several different jobs.
Split them into separate functions
and call them in turn.

Hand dumptypestructs a list of dcls,
rather than reading the global.

Rename dumpptabs for (marginal) clarity.

This is groundwork for compiling autogenerated
functions concurrently.

Passes toolstash-check.
