gopls/internal/golang: support extract variable at top level

This CL causes the refactor.extract.{variable,constant}
logic to support extractions outside of statement context,
inserting a new package-level declaration.
Previously, it returned an error.

Also, use "k" as the basis for choosing names for new constants.

Also, simplify generateAvailableName et al.

Fixes golang/go#70665
