Changes how JSON formatting works for fields supporting presence

Fixes #7486.

Note that this changes the behavior for message fields where
"WithFormatDefaultValues(true)" has been specified. This is
effectively fixing a bug, but will need to be noted in the release
notes.

Basically, FormatDefaultValues only affects fields that don't
support presence - most commonly, singular primitive non-optional
fields in proto3.
