Utils: Turn "Util.asciify" into a plain macro

This monves the asciify function to stringutils and makes it directly
available as "asciify:" prefix macro, so that the generation of a
default build path does not go through JavaScript.

"Util.asciify" remains available as core JavaScript extension for the
case that it is used by third party code/wizards.

This change also adds a test to tst_stringutils
