Nicholas Bishop 559602b9e8 Fix lowering crash in EmitAggregateInitializer (#7920) 
When `FindStorageArgForInitializer` is called from
`EmitAggregateInitializer` on a `SpliceInst`, that `SpliceInst` is
expected to have a constant `InstValue`. That may only be true in the
function specific though.

The `SpecificId` in `FindStorageArgForInitializer` defaults to `None`
and can't be set by the caller. Add a new
`FindStorageArgForInitializerInSpecific` that takes the `SpecificId` and
corresponding `File`. The original `FindStorageArgForInitializer` is now
a wrapper around the new function. This allows
`EmitAggregateInitializer` to set the appropriate `SpecificId`.

Fixes https://github.com/carbon-language/carbon-lang/issues/7873
