Promise.withResolvers is always polyfilled even when not desired

[char]

In our use case we are supplying our own polyfill for everything already so we set target to "Latest" to avoid dnt polyfills -- but since Promise.withResolvers is hardcoded to always polyfill, it's breaking our dnt generation runs:

src/_dnt.polyfills.ts:1:9 - error TS2669: Augmentations for the global scope can only be directly nested in external modules or ambient module declarations.

1 declare global {
          ~~~~~~

error: Uncaught (in promise) Error: Had 1 diagnostics.
          throw new Error(`Had ${diagnostics.length} diagnostics.`);

[char]

What do we think about a change where there are no polyfills introduced at all for ScriptTarget::Latest ? Or some different way to opt out of polyfills altogether

[dsherret]

That would be good. It would be nice to be able to more easily opt out of polyfills too.
