Igor Sheludko 3c57ad2121 [builtins] Port String.prototype.substr to Torque 
... and refactor String.prototype.substring.

This is done to simplify cleaning up callers of ConvertToRelativeIndex()
in a follow-up CL.

This CL also introduces Smi-overflow friendly helper function
  ClampToIndexRange(index: JSAny, min: uintptr, max: uintptr): uintptr

which can be used in other String builtins as a better alternative to
  NumberMin(NumberMax(value, min), max)
pattern.
