[release-branch.0.24] gopls: fix the build with go1.25
Turn the compile-time error in AddExistingFiles into a runtime panic,
and avoid it by delegating to the FileSet.AddExistingFiles method on
go1.25.
Also disable broken tests. Most of the breakage is related to
go/packages or the importer, as there was an export data change that is
not ported to this branch.
