Defaulted properties should not be injected

[seancorfield]

Thanks to @mjclemente on the CFML Slack for causing me to observe that a property with a default most likely does not represent a dependency (since dependencies don't have defaults).

Accordingly, I'm going to add omitDefaultedProperties but default it to true in 4.0 (a potentially breaking change). I'm also going to change the default for omitTypedProperties to true for the same reason and for consistency. Also a potentially breaking change (for folks who do not currently use that setting).

Needs documenting with a note that this is a breaking change.

Soving the BREAKING aspect by adding a changes document for the 4.0 documentation!
