Add literal picture recording mode, triggered by a compile time switch.

Add literal picture recording mode, triggered by a compile time switch.

This is helpful to record SKPs from Chrome as a fair bootstrapping source for
SkRecord.  Without this sort of switch, a good bit of SkPicture's cleverness is
baked into the SKP, and thus SkRecord looks unfairly good.

Tested by defining SK_RECORD_LITERAL_PICTURES and running dm --match
~optimizations.  By design that GM will never pass in literal mode.
