[SandboxVectorizer][NFCI] Fix use of possibly-uninitialized scalar. (#122201)
The `EraseCallbackID` field is not always initialized in the ctor for
SeedCollector; if not, it will be used uninitialized by its dtor. This
could potentially lead to the erasure of a random callback, leading to a
bug.
Fixed by making `CallbackID` an opaque type, which is always
default-initialized to an invalid ID.
