Move macros from TestClassDef.h to Test.h

Move macros from TestClassDef.h to Test.h

Motivation: those macros don't make any sense without the definitions
in Test.h.

I have talked to Mike about this over email. I told him I was working on this. I
got sick. Word does mean nothing here? The faster wins?

I did know you were working on this, but Hal did not.  I don't think I would
have encouraged him to start working on this had he asked me, but he certainly
doesn't have to ask me or ask anyone else to write some code and post a
changelist.  No one can (or should) prevent anyone from proposing any
improvement to Skia.  Sometimes this means work is duplicated.  When this
happens, the best available change does win, or rather, Skia wins sooner when we
check in a good change sooner.

If you think I promised to wait for you to make this change, we have
miscommunicated.  While we all try not to duplicate each other's work, this is
only for efficiency, not for territory.  I understand authorship is important to
you, but authorship is not particularly important to Skia the software library. 
You are welcome to have other priorities, but Skia can only ever care about the
code itself.

Your changes to Skia are welcome.  But I am concerned that our opinions are
diverging on how to productively contribute to Skia.

I would not have written the change if I knew you were working on it.  In fact,
your changes to simplify the test macros inspired me!
