Update PropertyMapper to better support nullability

Refactor `PropertyMapper` so that it no longer calls adapter or
predicate methods by default when the source value is `null`. This
effectively makes all default calls the same as using
`alwaysWhenNotNull` in the previous generation of the code.

For the limited times when you do need to deal with `null` values, the
new `always()` method can be used.

For example,

	map.from(source::method).to(destination::method);

Will not call `destination.method(...)` if `source.method()` returns
`null`.

Where as:

	map.from(source::method).always().to(destination::method);

Will call  `destination.method(null)` if `source.method()` returns
`null`.

This update provides clearer semantics for the API and allows for better
JSpecify nullability annotations. It has also simplified much of our
existing property mapper code.

Closes gh-47024
