SkQP: make_gmkb, gm_knowledge (GM Knowledgebase)

Add a real implementation for gm_knowledge.h  This depends on
the presence of files in the form $GMK_DIR/foo/{max,min}.png

The implementation also writes out failures in a report directory.

Add a utility: experimental/make_gmkb which is a stand-alone
go executable that generates the foo/{max,min}.png data.

tools/skqp/README.md has instructions on running SkQP.

Also: add SkFontMgrPriv.h
