8295944: Move the Http2TestServer and related classes into a package of its own

[GoeLin]

I backport this to simplify further backports. It's a refactoring of test infra.

I had to do resolves of Copyright, imports, and @test descriptions. A row of tests are not in 17.
In detail:

test/jdk/java/net/httpclient/AsFileDownloadTest.java
Needs resolve because earlier changes were al

test/jdk/java/net/httpclient/AsyncExecutorShutdown.java
Introduced in 19 by "8277969: HttpClient SelectorManager shuts down when custom Executor rejects a task"
This is a bug fix one wants to have in 17 at first sight, but it is a big change
and it had several follow ups. So better don't backport as prerequisite.

test/jdk/java/net/httpclient/CancelRequestTest.java
Resolved Copyright.

test/jdk/java/net/httpclient/CancelStreamedBodyTest.java
Introduced in 20 by "294916: Cancelling a request must eventually cause its response body subscriber to be unregistered"
This fix has many prereqs that would need to be backported. Omit.

test/jdk/java/net/httpclient/DigestEchoClient.java
Resolved Copyright.

test/jdk/java/net/httpclient/ExecutorShutdown.java
As above introduced by "8277969: HttpClient SelectorManager shuts down when custom Executor rejects a task". Omit.

test/jdk/java/net/httpclient/ExpectContinueTest.java
Introduced in 20 by "8286171: HttpClient/2 : Expect:100-Continue blocks indefinitely when response is not 100"

test/jdk/java/net/httpclient/HeadTest.java
Resolved Copyright and imports.
"8276559: (httpclient) Consider adding an HttpRequest.Builder.HEAD method to build a HEAD request." which came in 18
is a new feature with CSR that changed the imports.

test/jdk/java/net/httpclient/HttpClientLocalAddrTest.java
Introduced in 19 by "8209137: Add ability to bind to specific local address to HTTP client". A new
feature. Omit.

test/jdk/java/net/httpclient/ISO_8859_1_Test.java
Resolved Copyright

test/jdk/java/net/httpclient/MappingResponseSubscriber.java
Resolved imports.

test/jdk/java/net/httpclient/Response1xxTest.java
Introduced in 20 by 8292044: HttpClient doesn't handle 102 or 103 properly. Omit.

test/jdk/java/net/httpclient/SpecialHeadersTest.java
Resolved due to context.

test/jdk/java/net/httpclient/http2/IdleConnectionTimeoutTest.java
Was added by 8288717: Add a means to close idle connections in HTTP/2 connection pool in 20. Omit.

test/jdk/java/net/httpclient/http2/PushPromiseContinuation.java
Was added by 8263031: HttpClient throws Exception if it receives a Push Promise that is too large in 19. Omit.

test/jdk/java/net/httpclient/http2/UserInfoTest.java
Was added by 8292876: Do not include the deprecated userinfo component of the URI in HTTP/2 headers in 20. Omit.

test/jdk/java/net/httpclient/httpclient-localaddr-security.policy
Was added by 8209137: Add ability to bind to specific local address to HTTP client in 19. Omit.

test/jdk/java/net/httpclient/lib/jdk/httpclient/test/lib/common/HttpServerAdapters.java
Omitted Copyright, was already updated.

test/jdk/java/net/httpclient/lib/jdk/httpclient/test/lib/http2/Http2TestExchangeImpl.java
test/jdk/java/net/httpclient/lib/jdk/httpclient/test/lib/http2/Http2TestServer.java
test/jdk/java/net/httpclient/lib/jdk/httpclient/test/lib/http2/Http2TestServerConnection.java
test/jdk/java/net/httpclient/lib/jdk/httpclient/test/lib/http2/OutgoingPushPromise.java
Resolved Copyritht and in some the package statement.

Update:
Our testing showed that ConnectionReuseTest.java has to be adapted. See third commit.
It was crafted after this change and had to be adapted to the old location of the test helpers when being backported.
This test passes with the changes.
