Prior to this commit, the `ApplicationContext` couldn't start with a
JDK-proxied `HikariDataSource` as the JMX auto-configuration was
attempting to inject a (too narrowed) `HikariDataSource`.

This commit rather injects a regular `DataSource` and attempt to unwrap
it as a `HikariDataSource`.

  Add Netty Compression support

Closes gh-12268

Reactor Netty 0.7.5 now supports all Compression options.
Unlike previous Reactor Netty versions, the minimum compression
threshold is now based on the content-length instead of
accumulating for a while the data.

Closes gh-12233

Update `EndpointRequest` to that the `PathMappedEndpoints` bean is
optional. A missing bean is treated as if there are no path mapped
endpoints.

Fixes gh-12238

Update `WebMvcTypeExcludeFilter` to include `WebSecurityConfigurer`
beans.

Fixes gh-12275

Fix test failing due to commit d6649678.

See gh-12238

Update `ApplicationContextRequestMatcher` and
`ApplicationContextServerWebExchangeMatcher` to use a supplier for
the context, rather than the context itself.

This allow exceptions to be propagated to subclasses which may choose
to deal with them.

See gh-12238

Update `spring-boot-actuator-autoconfigure` so that it no longer has
a dependency on `spring-boot-test-autoconfigure`. This will allow us to
add test support for actuator concerns in the future if we need to.

Fixed gh-12270

This commit simplifies the HTTP compression configuration for Reactor
Netty servers.

Also, this commit removes a test for the
`server.compression.min-response-size` support, as this is only
supported when the HTTP response contains a `Content-Length` header.
Since most Spring WebFlux responses are using
`Transfer-Encoding: chunked`, we should not test for that case.

See gh-12268

Previously, if the project's group, name, or version changed the
BuildInfo task would still be considered up-to-date as the values of
the project's properties were not reflected in the fields of the
BuildInfo instance.

This commit updates BuildInfo to copy the value of the project's
property to the corresponding BuildInfo field when the property is
read using its getter method on BuildInfo.
