make matrix serialization private

Moves readFromMemory, writeToMemory to private section.
No sign that these are called from google3, android,
chromium, but function names are common enough that
it's hard to know for sure.

These are used inside templates internally and for
testing, so it is not quite as simple as adding alternate
entry points in SkMatrixPriv.
