Truncate string attributes in the accessibility tree 

Adds the helper function
BlinkAXTreeSource::TruncateAndAddStringAttribute, which truncates string
attributes when Blink's tree is serialized for accessibility. String
attributes are truncated at BlinkAXTreeSource::kMaxStringAttributeLength
bytes, currently set to 10000 bytes.
