Austin Eng 9756030d4e fuzzer: Implement BuildImpl for msl/hlsl Options structs 
The default implementation of this was generating random data for
the underlying pointers of std::unordered_map, leading to crashes
when the map was accessed. This CL populates the map in a
structured manner with pseudo-random data.

Ryan Harrison e7ca884b3d Add seed value constructor to DataBuilder 
This is needed for experimenting with alternate fuzzing frameworks
that can generate a seed value without needing to hash the input.
