Remove SkNEW_APPEND_TO_TARRAY.

The use of SkNEW_APPEND_TO_TARRAY is now better served by
SkTArray::emplace_back(...) which should now be used instead. The
existing users of SkNEW_APPEND_TO_TARRAY are converted and the code
relating to SkNEW_APPEND_TO_TARRAY is removed.

TBR=reed
This only removes code. The file should also be made private.
