* GH-3897: Deprecate `ChannelSecurityInterceptor`
Fixes https://github.com/spring-projects/spring-integration/issues/3897
Spring Security has deprecated `AccessDecisionManager` and all its infrastructure
in favor of `AuthorizationManager`
* Deprecate and AOP `ChannelSecurityInterceptor` and all its infrastructure,
including `@SecuredChannel` and respective XML configuration.
The `AuthorizationChannelInterceptor` added to respective channels for security
or configured as a global channel interceptor fully covers the previous AOP configuration
* Fix deprecation warnings in other tests with security
* Fix language in docs

* * Remove `forRemoval` attr from `@Deprecated` markers for Security classes:
looks like to mark `@Deprecated` and even `@SuppressWarnings("deprecation")`
don't silence warnings on compilation
