Plugins: Introduce singular capabilities for activating and deactivating individual plugins.

This introduces the following meta capabilities:

* `activate_plugin`
* `deactivate_plugin`
* `deactivate_plugins`

The singular `activate_plugin` and `deactivate_plugin` capabilities are used along with the corresponding plugin name when
determining whether or not a user can activate or deactivate an individual plugin.

The plural `deactivate_plugins` capability is used in place of the existing `activate_plugins` capability when determining
whether a user can deactivate plugins.

Each of these new meta capabilities map to the existing `activate_plugins` primitive capability, which means there is no
change in existing behaviour, but plugins can now filter the capabilities required to activate and deactivate individual
plugins.

Fixes #38652
