avoid type-live-for-region obligations on dummy nodes

Type-live-for-region obligations on DUMMY_NODE_ID cause an ICE, and it
turns out that in the few cases they are needed, these obligations are not
needed anyway because they are verified elsewhere.

Fixes #46069.

Beta-nominating because this is a regression for our new beta.
