go/ssa: speed up TestTypeparamTest by loading tests once

Previously, TestTypeparamTest constructs a go module for each file
under test/typeparam and uses packages.Load to load it. However, the
packages.Load utilizes the 'go list' underlying and it costs a lot.
As a result, this made the test 50x slower.

This change tries to put each file under a separated package
in the same go module so 'go list' will be used only once.

It supports to skip the test if the test/typeparam under GOROOT doesn't
exist.

Fixes golang/go#70078
