go/analysis/internal/checker: fix panic due to nil Pass

This CL documents that that internal.Pass backdoor accessor
function (renamed to ActionPass for clarity) may return nil
if the action was never executed, and adds defensive checks.

Also, remove go1.22 transitional iterator.

Thanks to cuishang for reporting and investigating.

Fixes golang/go#75358

[release-branch.0.25] 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. Fewer test were broken here than in
release-branch.0.24, because this branch include support for the new
export data.

[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.
