Release 912.0.0 (#8451)

This release includes the following package:

- `@metamask/base-controller` 9.0.1 -> 9.1.0

This release is necessary because the `${Controller}:stateChange` event
is now deprecated in favor of `${Controller}:stateChanged`. More
importantly, `ControllerStateChangedEvent` is now available for use in
controller packages so that engineers can support the new event in their
messenger types.

> [!NOTE]
> **Low Risk**
> Primarily a dependency/version bump across many packages; risk is
limited to any downstream behavior/type changes introduced by
`@metamask/base-controller@9.1.0` (new `:stateChanged` event) affecting
consumers at build/runtime.
> 
> **Overview**
> **Publishes `@metamask/base-controller@9.1.0`** and updates its
changelog/compare links for the new release.
> 
> **Propagates the bump** by updating dozens of controller packages’
`package.json` dependencies and `CHANGELOG.md` entries from
`@metamask/base-controller@^9.0.1` to `^9.1.0`, with corresponding
`yarn.lock` updates.
