#2099

Short description and why it's useful

I added tiny module just to have sth new in this release. Also depreciated some parts of the app that were meant to be depreciated in 1.7 (unfortunately due to 2 weeks off I wouldnt be able to depreciate everything we planned to in favour of doing performance optimisation)

• added Web Share API module
• depreciated old way of extending VS stores (extendStore)
• removed unused ValidationError class from Ajv
• merged store helpers with core helpers and deleted duplicated ones (just libs and types left!)
• cleanup of unused imports

Screenshots of visual changes before/after (if there are any)

(if you made any changes in the UI layer please provide before/after screenshots)

Screenshot of passed e2e tests (if you are using our standard setup as a backend)

(run yarn test:e2e and paste the results. If you are not using our standard backend setup or demo.vuestorefront.io you can ommit this step)

Upgrade Notes and Changelog

• No upgrade steps required (100% backward compatibility)
• I've updated the Upgrade notes and Changelog on how to port existing VS sites with this new feature

Contribution and currently important rules acceptance

• I read and followed contribution rules
• I read the TypeScript Action Plan and adjusted my PR according to it
• I read about Vue Storefront Modules and I am aware that every new feature should be a module

Cool feature:)
Only i'd left old helpers with warning and instruction to assure smooth upgrade.
