Reviewed by Darin Adler.
Introduce SafeTextMarkerData as an alternative to TextMarkerData, which uses
a WeakPtr for `node` instead of a raw pointer. TextMarkerData currently has
to keep using a raw pointer because memcpy() / memcmp() are used with this
type's bytes. However, we should use SafeTextMarkerData wherever possible
and this patch starts doing some adoption to address the crash.
