Generate and store serialized reports about rebuild components

[befeleme]

Opening PR for visibility, will play with the stored data and decide about tweaks.

Example extension of the status page:

This is ready for review.

Whenever jobs.py is run, two reports will be generated; should be stored in git with progress.pkgs. I'll point to the target branch as a source for status page.

changes:

• buildable/non-buildable bconds are now stored in lists
• bcond strings are processed, so only the name of the combination is stored, not the whole component::bcond:::: string
• flipped the prerel_abi_blocked to prerel_abi_compatible key, ensuring True means a good thing

New preview:

I'm going to split the PR and: ship the commonly blocking report; which is smaller and immediately actionable (can be improved over time); keep the full availability report in draft, as while churning data I keep stumbling upon not enough information, and also I suspect I'm identifying small bugs in data handling in the scripts.
