Make parameters ordered in SearchSpace

[esantorella]

Summary: This PR: Changes SearchSpace.parameters from a dict to an OrderedDict.

Context: In benchmarking, the order of parameters matters because parameters can be converted to a tensor. In the current Python version, this should work even without using OrderedDict because dicts are insertion-ordered, but this isn't an officially supported language feature or guaranteed to last.

One downside is that by annotating the parameters as an OrderedDict, we can't also annotate them as an immutable Mapping. For now, this is fine, because the parameters are mutated, so we can't annotate them as immutable anyway.
