This commit removes the deallocation capabilities of one-shot-bufferization. One-shot-bufferization should never deallocate any memrefs as this should be entirely handled by the ownership-based-buffer-deallocation pass going forward. This means the `allow-return-allocs` pass option will default to true now, `create-deallocs` defaults to false and they, as well as the escape attribute indicating whether a memref escapes the current region, will be removed. A new `allow-return-allocs-from-loops` option is added as a temporary workaround for some bufferization limitations.
