Idea: Automatically validate sqlite versions

We manually maintain a list of known-bad SQlite versions in meson.build.

We could catch problems earlier if we automatically tested against multiple SQLite versions.

Here's a proposal.

1. Add files sqlite3_versions_tested and sqlite3_versions_known_bad to Git. Proposed format:

     3.55.1: Slow queries due to X
     3.34.0: Broken, see https://gitlab.gnome.org/...

2. Modify meson.build to read these file using files module and parse contents into a dict. Replace the existing hardcoded list. Meson should error if SQLite version is in known_bad list, and warn if it's not in tested list.

3. Add a new CI job that loads sqlite_versions_tested, downloads and builds each version from Gitlab in sequence and runs tracker.git test suite against it.

When a new SQLite version is released, Meson will warn about it until we add it to the sqlite3_versions_tested file and make sure it works.
