I have verified locally that nothing draws differently.
Motivation:
* SK_SIMPLE_GM makes it easier to write a GM.
* Reducing 1100 lines of code makes maintenance easier.
* Simple GMs are easy to convert to Fiddles.

This patch addresses two issues:
1) Textblobs with abandoned strikes were not properly regenerating.
2) Provided by ericrk - GrTextBlobCache removed blobs from |fCache| during freeAll, but left
potentially released blobs in the |fBlobList|. We now remove these from
|fBlobList| as well.
