cmd/compile/internal/syntax: make valid type parameter list in presence of errors

Make sure the parser fills in names and types for type parameter
lists, even in the case of errors.

While at it, adjust some of the test functions to accept generic
code and report all syntax errors.

Added offending source as test for types2.

Fixes #47996.
