feat(clerk-js,clerk-react,types,nextjs): Support assurance in `has()`

[panteliselef]

Description

This PR adds experimental support for has() with assurance.

has({ 
  __experimental_assurance: {
    level: 'L2.secondFactor',
    maxAge: 'A1.10min'
  }
})

Also I introduced a new shared utility called createCheckAuthorization exported from @clerk/shared that all other packages can use.
