Add support for delegate parameters

[maca88]

Example:

public class MethodWithDelegate
{
    public void Test()
    {
        Read(() => SimpleFile.Read());
    }

    public void Read(Action action)
    {
        action();
        SimpleFile.Read();
    }
}

Desired result

public partial class MethodWithDelegate
{
    public Task TestAsync()
    {
        return ReadAsync(() => SimpleFile.ReadAsync());
    }

    public async Task ReadAsync(Func<Task> action)
    {
        await action();
        await SimpleFile.ReadAsync();
    }
}

I think the title needs to be refined:)

Hmm what do you suggest? :) The idea of this issue is about parameter transformation e.g. from Action to Func<Task>, once the parameter would be marked to be asyncable then the argument would be also converted. The logic for converting the argument is already implemented.

I don't know. It's just you've had "Add better support for delegate arguments" now "Add support for delegate parameters". Or is it in the difference between "arguments" and "parameters"?

Yes. I know that the titles are almost the same but main difference is argument vs parameter. Transforming an argument is different from transforming a parameter. I'm open to suggestions for a better title name :)
