What kind of change does this PR introduce?

Feature

What is the current behavior?

Synchronous Components (islands) without any generator connected are causing many ERROR logs to be reported. Hundreds of errors are logged on real case large networks when OLF configured to solve all components which is quite inconvenient, and not really an error.

What is the new behavior (if this is a feature change)? Synchronous Components (islands) without any generator are now flagged as dead.

With new LoadFlowResult API (see https://github.com/powsybl/powsybl-core/pull/2767) and #918 we new report new NO_CALCULATION status for dead islands.

Notes:

DC Load Flow with this change will not solve islands without generators anymore. It was solving them before - in my opinion this is not a regular use case
AC Load Flow: islands with generators but no voltage regulation are not considered dead, a FAILED status is reported in the case of generators present but no voltage regulation.

Does this PR introduce a breaking change or deprecate an API?
