clean/deps: remove unused Babel plugins: transform-runtime, dynamic-i…

…mport (#837)

- transform-runtime is not used
  - its functionality will instead be added by the newer/better
    babel-plugin-polyfill-regenerator in a future commit/PR
  - move it to devDep as there is an integration test for it

- syntax-dynamic-import is not used
  - and it's also included in @babel/preset-env anyway

- these were added in bfc0590 to
  support `@wessberg/rollup-plugin-ts` but were not rolled back when
  that was rolled back in 3989277
