refactor: convert blocksvg and block to ES6 classes (#5952)

* refact: move super call to top of block svg

* refact: run conversion script on block svg and block

* fix: make debug build happy

* fix: tests

* style: format

* fix: cleanup from rebase

* fix: use new.target instead of a new parameter

* fix: add more overridden casted methods to BlockSvg

* style: fix typos

* style: move override tags to the end of JSDoc

* fix: cleanup from rebase
