Block tunes as a popover

[TatianaFomina]

• Updates block tunes to use popover component. As a temporary solution, non-default block tunes are rendered as before and inserted to special area inside the popover.
• New getter blockSettings (naming could be discussed) is added to tunes interface. It allows to configure the way tune is displayed in the popover.

this is actually a problem as it makes the cypress dependency, and causing the following errors for the apps

Error: node_modules/@editorjs/editorjs/types/configs/index.d.ts:1:30 - error TS2307: Cannot find module 'cypress/types/bluebird' or its corresponding type declarations.
