feat: Bundle option without any external scripts

[benjackwhite]

Changes

Builds on top of @pauldambra 's great external scripts typing work and makes the external deps loader a separate extension that we can then include depending on the bundle

This allows someone to import specific modules such as

// No external module loading bundled
import posthog from 'posthog-js/dist/module.no-external'
// All external modules pre-bundled but still allows external things like site apps
import posthog from 'posthog-js/dist/module.full'
// All external modules pre-bundled and no external loading possible
import posthog from 'posthog-js/dist/module.full.no-external'

Checklist

• Tests for new code (see advice on the tests we use)
• Accounted for the impact of any changes across different browsers
• Accounted for backwards compatibility of any changes (no breaking changes in posthog-js!)
