SI-6843 well-positioned syntax errors for quasiquotes

This is achieved in a following way:

1. Similarly to toolbox quasiquotes can go away with wrapping for
   parsing purpose after introduction of `parseStats` and `parseRule`
   entry points.

2. In case of syntax error quasiquote computes equivalent corresponding
   position in the source code with the help of `corrrespondingPosition`
   mapper which relies on position data collected into `posMap` during
   code generation.
