Prior to this commit, the entry set of read-only HttpHeaders lost the
original headers' ordering.
The changes in commit ce7278aaf4 introduced a regression in the read-only
HttpHeaders support. Specifically, the implementation of entrySet() in
the internal ReadOnlyHttpHeaders class converted the original entry set
to an immutable, non-ordered set of immutable entries.
This commit fixes this issue by converting the original entry set to an
immutable, ordered set of immutable entries.

This commit prepends "[{index}] " to all custom display names
configured via @ParameterizedTest.
This provides better diagnostics between the "technical names" reported
on the CI server vs. the "display names" reported within a developer's
IDE.

Prior to this commit, there was no way to replace the Set-Cookie header
via MockHttpServletResponse. Specifically, an invocation of setHeader()
for the Set-Cookie header resulted in an additional Set-Cookie header
instead of replacing the existing one, which is in violation of the
contract for javax.servlet.http.HttpServletResponse.setHeader(...).
This commit refactors the internals of MockHttpServletResponse to ensure
that an existing Set-Cookie header is overwritten when set via an
invocation of setHeader(). This commit also verifies the expected
behavior for addHeader() and addCookie() with regard to multiple cookies.

Due to a bug (or "unintentional feature") in JUnit 4, overridden test
and lifecycle methods not annotated with @Test, @Before, @After, etc.
are still executed as test methods and lifecycle methods; however,
JUnit Jupiter does not support that. Thus, prior to this commit, some
overridden test and lifecycle methods were no longer executed after the
migration from JUnit 4 to JUnit Jupiter.
This commit addresses this issue for such known use cases, but there
are likely other such use cases within Spring's test suite.

The use of LinkedCaseInsensitiveMap, going back to 3.0, makes it
unnecessary to iterate over keys which can cause
ConcurrentModificationException.

This commit removes the JUnit 4 dependency from all modules except
spring-test which provides explicit JUnit 4 support.
This commit also includes the following.
- migration from JUnit 4 assertions to JUnit Jupiter assertions in all
Kotlin tests
- migration from JUnit 4 assumptions in Spring's TestGroup support to
JUnit Jupiter assumptions, based on org.opentest4j.TestAbortedException
- introduction of a new TestGroups utility class than can be used from
existing JUnit 4 tests in the spring-test module in order to perform
assumptions using JUnit 4's Assume class

This commit migrates parameterized tests in spring-core using the
"composed @ParameterizedTest" approach. This approach is reused in
follow-up commits for the migration of the remaining modules.
For a concrete example, see AbstractDataBufferAllocatingTests and its
subclasses (e.g., DataBufferTests).
Specifically, AbstractDataBufferAllocatingTests declares a custom
@ParameterizedDataBufferAllocatingTest annotation that is
meta-annotated with @ParameterizedTest and
@MethodSource("org.springframework.core.io.buffer.AbstractDataBufferAllocatingTests#dataBufferFactories()").
Individual methods in concrete subclasses are then annotated with
@ParameterizedDataBufferAllocatingTest instead of @ParameterizedTest or
@Test.
The approach makes the migration from JUnit 4 to JUnit Jupiter rather
straightforward; however, there is one major downside. The arguments
for a @ParameterizedTest test method can only be accessed by the test
method itself. It is not possible to access them in an @BeforeEach
method (see https://github.com/junit-team/junit5/issues/944).
Consequently, we are forced to declare the parameters in each such
method and delegate to a custom "setup" method. Although this is a bit
cumbersome, I feel it is currently the best way to achieve fine grained
parameterized tests within our test suite without implementing a custom
TestTemplateInvocationContextProvider for each specific use case.
Once https://github.com/junit-team/junit5/issues/878 is resolved, we
should consider migrating to parameterized test classes.

Deprecate all mutation methods in `MethodParameter` in favor of factory
methods that return a new instance. Existing code that previously relied
on mutation has been updated to use the replacement methods.
