Build Identifier: I20110310-1119

In Java, if I press Ctrl+Shift+Space within a method call I get a tooltip showing information about the required parameters or a dropdown to select one of the overloaded variants. This is not available in xbase.

Reproducible: Always

Steps to Reproduce:
parameter information:
in Tutorials.xbase, type ( | showing cursor position):
var str = "this is a string".codePointCount(|          )
in Java editor, I get a tooltip displaying the type, name and current (bold) argument. 

Overloaded variant selection:
in Tutorials.xbase, type ( | showing cursor position):
var substr = "this is a string".substring(|     )
in Java editor, I get a list of all possible overloaded variants.

Startet to implement parameter tooltips for content proposals and overloaded variants.

We should probably add a shortcut that brings this parameters hints up without invoking CA.

this feature is there (ParameterContextInformationProvider) but the impl seems broken
