Possibility to disable some polyfills

[MirKml]

In one of the latest releases, a huge polyfill for import.meta was added. However, the current LTS Node - 22 - supports import.meta fine. It’s clear that DNT has to support older Node versions, but the possibility to disable some polyfills is desired.

I also found this PR #441 - when script target is latest, no pollyfills are applied,
but it seems doesn't work, I set

compilerOptions: {
    lib: ["ESNext"],
    target: "Latest",
  },

and import.meta polyfill is still applied. Source of pollyfill isn't included but code is transformed into
globalThis[Symbol.for("import-meta-ponyfill-esmodule")](import.meta).dirname. This leads to error in generated code runtime.
