Spring Boot's testing support registers a DynamicPropertyRegistry as a
bean in the ApplicationContext, which conflicts with the
DynamicPropertyRegistry registered as a bean by the Spring TestContext
Framework (TCF) since Spring Framework 6.2 M2.
To avoid that conflict and to improve the user experience for Spring's
testing support, this commit introduces a DynamicPropertyRegistrar API
to replace the DynamicPropertyRegistry bean support.
Specifically, the TCF no longer registers a DynamicPropertyRegistry as
a bean in the ApplicationContext.
Instead, users can now register custom implementations of
DynamicPropertyRegistrar as beans in the ApplicationContext, and the
DynamicPropertiesContextCustomizer now registers a
DynamicPropertyRegistrarBeanInitializer which eagerly initializes
DynamicPropertyRegistrar beans and invokes their accept() methods with
an appropriate DynamicPropertyRegistry.
In addition, a singleton DynamicValuesPropertySource is created and
registered with the Environment for use in
DynamicPropertiesContextCustomizer and
DynamicPropertyRegistrarBeanInitializer, which allows
@DynamicPropertySource methods and DynamicPropertyRegistrar beans to
transparently populate the same DynamicValuesPropertySource.

Prior to this commit, MVC function endpoints would allow Server Sent
Event responses through `ServerResponse.sse()`. While this covers a
common use case for streaming responses, other technologies would
benefit from a "low-level", unopinionated streaming support.
This commit introduces a new `BodyBuilder.stream()` methods that enables
such use cases. Developers are in charge of setting the relevant HTTP
response headers beforehand, and then can write to the response as raw
`String`, `byte[]` or using complex objects and the configured message
converters for serialization.
Because each streaming protocol has different message separator
semantics, it is also the developers' responsibility to flush buffered
content to the network once a message has been fully written.

This aligns HttpHeaders with other places like ServletWebRequest and
DefaultWebExchange where an ETag is accepted as input.
It also allows us to remove quoting from places that delegate to
HttpHeaders#setETag since it now does that internally.
Closes gh-33412
Update checks whether quoting is needed to be more complete
than what we've used so far, making sure the there is both
opening and closing quotes independent of each other.

This commit exposes the unexpanded URI template used to build a
MockHttpServletRequest. This allows MockMvc users to retrieve that
information, in consistency with ExchangeResult in WebTestClient.

Since we now use asciidoctor-tabs instead of spring-asciidoctor-backends,
we no longer need the `role="primary"` and `role="secondary"` attributes
for tab groups.
Closes gh-33506
Prior to this commit, `ResponseBodyEmitter` woud accept a single
`Runnable` callback on each of its `onTimeout`, `onError` or
`onCompletion` methods. This would limit the developers' ability to
register multiple sets of callbacks: one for managing the publication of
streaming values, another one for managing other concerns like
keep-alive signals to maintain the connection.
This commit now allows multiple calls to `onTimeout`, `onError` and
`onCompletion` and will register all callbacks accordingly.
Closes gh-33356
