[🚀esl-utils]: extend `SynteticEventTarget` with ability to separate events

[ala-n]

As an ESL consumer, I want to be able to use SynteticEventTarget widely, so it should support EventTarget interface without restrictions.

It is proposed to make SynteticEventTarget respect passed event type.

Priority: Minor.
