Adds a "tag" system so that entries of dawn.json can be conditionally
emitted in different configurations. With a few more dawn.json changes,
this will enable generating the exact upstream header.

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.
