ci: generate DB fixtures on-demand instead of committing binaries

Remove spawn_and_move.tar.gz and simple.tar.gz from git. These were
built on macOS (16KB page size) and fail on Linux CI (4KB page size)
with MDBX_CORRUPTED. Instead, add a `generate-db-fixtures` CI job
that compiles and runs `generate_migration_db` on the same platform
where tests run. Uses actions/cache keyed on db version + dojo ref
so full generation only happens on cache miss.
