Sk_API for SkImageGenerator and SkInstallDiscardablePixelRef
Added SK_API to SkImageGenerator (already in include/).
Moved SkDiscardablePixelRef::Install to SkInstallDiscardablePixelRef,
added SK_API to that function, and moved declaration to
SkImageGenerator.h
This keeps the SkDiscardablePixelRef internal to Skia, but exposes a
method to install it into a bitmap.
Modifed tests that rely on this functio to use new version.
