ggml-webgpu: Fix some binding alias issues to support all archs, fix recurrent-state-rollback test (#25931)

* Add overlap glu variant to support all archs, fix recurrent-state-rollback test

* format

* Fix all arch overlapped ranges

* format

* diagnose bus error on apple ci

* More testing

* more testing

* more targeted testing

* Fix bug in alignment for > 4gb buffer offsets

* Fix bug in view offsets

* Try avoiding multi_buffers

* not fixed yet, more logging :(

* Handle edge case in set_rows

* Try looking at view source

* Skip deepseek32 for now and clean up trace infrastructure

* simplify skipping

* last cleanup

* actually final cleanup

* update handling of overlap

* format

* try skipping other failing model
