Apex Language Server should support methods in anon-apex #5312

[przemekrcloudity]

Is your feature request related to a problem? Please describe.

In anonymous apex scripts, defined functions aren't auto-completed. For example in code

String key(Integer x, Integer y) {
    return x + '  ' + y;
}

System.debug(key(10, 10));

method key is not autocompleted.

Whats more, parameters are not visible inside function, which means that autocompletion for both these parameters and theirs methods and properties is not working.
Variables defined inside method are visible though.

Parameters autocompletion	Variables autocompletion
