Plugin Dependencies: Remove auto-deactivation and bootstrapping logic.

Automatic deactivation of dependents with unmet dependencies requires a write operation to the database. This was performed during Core's bootstrap, which risked the database and cache becoming out-of-sync on sites with heavy traffic.

No longer loading plugins that have unmet requirements has not had a final approach decided core-wide, and is still in discussion in #60491 to be handled in a future release.

The `plugin_data` option, used to persistently store plugin data for detecting unmet dependencies during Core's bootstrap, is no longer needed.

Follow-up to [57545], [57592], [57606], [57617].

Props dd32, azaozz, swissspidy, desrosj, afragen, pbiron, zunaid321, costdev.
Fixes #60457. See #60491, #60510, #60518.
