Remember value of IsImplSidePaintingEnabled

Command line arguments are constant at runtime, but the function
cc::switches::IsImplSidePaintingEnabled() does two searches through
the list of arguments every time it's called, and it's called every
time we record a SkPicture.

With this patch, the function remembers the value determined by the
first call and avoids repeating the searches on subsequent calls.
