fix(OIDC): back channel logout work for custom UI (#9487)

# Which Problems Are Solved

When using a custom / new login UI and an OIDC application with
registered BackChannelLogoutUI, no logout requests were sent to the URI
when the user signed out.
Additionally, as described in #9427, an error was logged:
`level=error msg="event of type *session.TerminateEvent doesn't
implement OriginEvent"
caller="/home/runner/work/zitadel/zitadel/internal/notification/handlers/origin.go:24"`

# How the Problems Are Solved

- Properly pass `TriggerOrigin` information to session.TerminateEvent
creation and implement `OriginEvent` interface.
- Implemented `RegisterLogout` in `CreateOIDCSessionFromAuthRequest` and
`CreateOIDCSessionFromDeviceAuth`, both used when interacting with the
OIDC v2 API.
- Both functions now receive the `BackChannelLogoutURI` of the client
from the OIDC layer.

# Additional Changes

None

# Additional Context

- closes #9427
