Jakob Gruber 3b4b736a90 [snapshot] Refactor the FixedRawData bytecode
From recent discussions on https://crrev.com/c/2057355 it became clear
that the FixedRawData serializer bytecodes need to be refactored. This
CL

- updates documentation to correctly specify that data length is given
in kTaggedSize unit, and
- changes the way smi roots are serialized s.t. deserialization no
longer needs hacks to be correct on big-endian architectures and when
(theoretically) deserializing sequences of smi roots. We do this by
serializing the full object slot for smi roots instead of just the
smi contents.
