Now only the immediately preceding jsdoc of a node is retrieved by getJSDoc, although it still does the correct non-local lookup for nodes like ParameterDeclaration.
This doesn't change parsing or binding, which use the per-node Node.jsdoc property directly. But it does change everything that relies on getJSDoc, which includes the checker and language service.
Fixes #32062, which contains the analysis that justifies the change.
