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.
