Brian Ho 5346e770c9 Add helper functions to iterate over ChainedStructs
This CL adds two helpers for more ergonomic processing of
ChainedStructs.

1. FindInChain(): Iterates through the chain and automatically
   casts the ChainedStruct into the appropriate child type before
   returning.
2. ValidateSTypes(): Verifies that the chain only contains structs
   with sTypes from a pre-defined set. This also allows the caller
   to specify one-of constraints.
3. ValidateSingleSType(): Verifies that the chain contains a
   single struct with a specific sType or is an empty chain. This
   is a common case of |ValidateSTypes()| and is separated out as
   a fast-path.
