macro-based string interpolation formatter

This commit provides a macro based string interpolation formatter.
The macro is implemented in MacroImplementations.scala.

In order to still be able to build a new STARR, the implementation
in StringContext.f is not yet changed. This will be replaced in
a later commit.
