build: add support for skipping exercises

Browse source 
Currently, exercises not working with the current Zig compiler are
commented. This is problematic, since the exercise key and exercise
index are no longer consistent.

Add the skip field to the Excercise struct.  Update ZiglingStep to
support it and add a new SkipStep step to support it when using the
standard build step.
