GH-3083: Support @Header with dotted literals

Browse Source 
Fixes https://github.com/spring-projects/spring-integration/issues/3083

`@Header("foo.bar")` means extract property `bar` from header `foo`.

Support `@Header("'foo.bar'")`, meaning get the value of header `foo.bar`.

**cherry-pick to 5.1.x, 4.3.x**
