[static registrar] Handle metadata token lookup failure gracefully.

[rolfbjarne]

Change the static registrar to fail gracefully if it can't compute a metadata token
for a given metadata item, and instead fall back to doing the lookup of whatever
we need at runtime.

This is a step towards making per-assembly static registrar working.

Ref: #12067.
