Add ViewMatcher withContentDescription with resource identifier instead of String

[JolandaVerhoef]

Currently it's only possible to match using a String content description. I think

Steps to reproduce:

1. Try to match a view based on it's content description id

Observed Results:

• Compile error: Pass String instead of int

Expected Results:

• Would like to be able to match on id, so that localisation doesn't give problems

Relevant Code:

val navigationIcon = KView {
      withContentDescription { R.string.cd_hamburger_icon }
  }
