Fixes gh-9542

This commit removes the only use of the `javax.annotation.Resource`
annotation from the codebase. This ensures that injection point are
only defined with Spring's annotation model.

Previously, @AutoConfigureJsonTesters only imported
JsonTestersAutoConfiguration and relied on something else pulling in
the Jackson and GSON auto-configuration upon which it depends. This
worked with @JsonTest which imported those auto-configurations. It
did not work with @SpringBootTest which would use
@EnableAutoConfiguration and the ordering was then wrong and
JsonTestersAutoConfiguration would be processed before the Jackson
and GSON auto-configurations had a chance to create the beans that
JsonTestersAutoConfiguration needs.

This commit updates the spring.factories configuration for
JsonTestersAutoConfiguration so that it imports
JacksonAutoConfiguration and GsonAutoConfiguration.
Appropriate @AutoConfigureAfter has also been added to
JsonTestersAutoConfiguration to ensure that it is considered after
JacksonAutoConfiguration and GsonAutoConfiguration.

Lastly, ExampleJsonApplication and associated classes have been moved
into an app sub-package to prevent its component scanning from
pulling in JsonTestersAutoConfiguration as if it were user
configuration.

  Ensure compatibility with Spring Session module split

Closes gh-9554

This commit updates Spring Session auto-configuration to ensure
compatibility with extraction of `SessionRepository` implementations into
separate Spring Session modules.

Previously, both Repackager and the Grade plugin used the JRE's
standard ZipOutputStream when creating a fat jar or war file. This
resulted in entry names that needed UTF-8 encoding to become
corrupted.

This commit updates both to use Commons Compress'
ZipArchiveOutputStream and to configure the stream's encoding and
each entry's Unix mode. This ensures that names are encoded using
UTF-8 and can be read back in correctly by common zip tools.

Closes gh-9405

This commit makes sure that each test runs with the proper datasource
auto-configuration and with an isolated embedded database. This allows
to restrict each test to only what it is supposed to do (rather than
disabling initialization to work around the fact that database is not
in a proper state because it is shared).
