Closes gh-16629:

Polish contribution to use a factory method in `AbstractJsonMarshalTester`
rather than additional constructor arguments.

Also change the `JsonContent` tests so that the `Configuration` constructor
is package private. This keeps JsonPath classes out of our public API, at
the expense of limiting custom JsonPath configurations to just our code.

See gh-16629

Update `JacksonTester` so that the JsonPath instance is explicitly configured
with both a `JacksonJsonProvider` and a `JacksonMappingProvider`.

Prior to this commit, the handling of special characters was not symmetrical
between the serialization (handled via the JacksonTester) and the parsing (handled
via JsonPath) due to the fact that JsonPath used `SimpleJson` as its parser.

  Polish "Improve DefaultCookieSerializer auto-configuration"
  Improve DefaultCookieSerializer auto-configuration

Closes gh-16513

Spring Session's own configuration support (i.e.
SpringHttpSessionConfiguration) will configure the default
DefaultCookieSerializer with rememberMeRequestAttribute if
SpringSessionRememberMeServices bean has been detected in the
application context.

In contrast, Spring Boot's auto-configured DefaultCookieSerializer does
not do this which results in a different out-of-the-box experience for
users that rely on Spring Session's remember-me integration.

This commit improves Spring Session DefaultCookieSerializer
auto-configuration to match Spring Session's behavior and make the
auto-configured DefaultCookieSerializer aware of
SpringSessionRememberMeServices bean.
