Implement absoluteImports option

[nicolo-ribaudo]

This option is similar to @babel/transform-runtime's absoluteRuntime option.
It has been renamed because polyfill providers don't injected imports to @babel/runtime.

PR for @babel/transform-runtime: babel/babel#8435

This option is an improvement over @babel/transform-runtime's, since it also works for polyfills attached to the global scope.

Ref: babel/babel#12035

Will this also benefit Babel 7, or only Babel 8+?

[nicolo-ribaudo]

This plugin is already fully compatible with Babel 7: the only difference is that in Babel 8 it will be the only way to inject polyfillls.

We'll discuss if it makes sense to add an equivalent option, or if we'll only implement it here to encourage migration.

Could you provide an example of how this might be configured?

im guessing like in the migration docs, we wouldn't use preset-env's corejs options anymore but would use this plugin:

  "plugins": [
    ["polyfill-corejs3", {
      "method": "usage-global",
      "absoluteImports": true
      // ..
    }]
  ]
