Expose "full" dexpreopt.config

1. Instead of 'slim' config, use full config even for libs
2. Define moduleJSONConfig for fields which cannot be converted to JSON
field directly(Path type field, ProfileBootListing,
DexPreoptImagesDeps are added in this CL) and exclude fields which is
convertible(DexPreoptImageLocations)
