fix(java): list dependencies' implementations after the project's in Go to Implementation (#1644)

Go to Implementation on a type or method declared in a dependency listed only the project's implementations once the project had one. openidea.java.implementations (java-usages 1.5.0) now answers {locations, complete}, complete when the type is declared in the sources, and also searches the Kotlin bridge's classes. When not complete, the chooser opens with the project's implementations (searching…) through the new lsp_goto_implementation channel and fills in the dependencies' when the standard request ends; closing it cancels the search.
