Add writeToMemory() API to SkColorSpace
New API mirrors the form of similar APIs in SkRegion,
SkMatrix, etc.
This also fixes a bug:
SkImageInfo appears in a object that Chrome stores in
discardable memory. So when sk_sp<SkColorSpace> was added
to SkImageInfo a leak was introduced. We'll use this new
method and deserialize to store the SkColorSpace in the
discardable object.
