Extract functions to read spec files from different format (#35094)
This commit makes explicit the format version of the spec file we are reading from. Before there were different functions capable of reading some part of the spec file at multiple format versions. The decision was implicit, since checks were based on the structure of the JSON without ever checking a format version number. The refactor makes also explicit which spec file format is used by which database and lockfile format, since the information is stored in global mappings. To ensure we don't change the hash of old specs, JSON representations of specs have been added as data. A unit tests checks that we read the correct hash in, and that the hash stays the same when we re-serialize the spec using the most recent format version.
