Ryan Nowak 6f383a0f0f Adds support for 'Context' parameters on components (#1470) 
Adds support for 'Context' parameters on components

This change allows you to set the parameter name of a parameterized child content by using the `Context` attribute on the component. The `Context` attribute will be defined (and shown by completion) when the component has one or more declared parameterized (`RenderFragment<>`) child content parameters.

This is nice for cases where you are using implicit child content:

```
<ol>
  <Repeater Items="People" Context="person">
    <li>@person.FirstName</li>
  </Repeater>
</ol>
```

 or, when you have multiple child content elements and want them all to have the same parameter name:

 ```
<MyComponent Items="People" Context="person">
    <ChildContent1><div>@person.FirstName</div></ChildContent1>
    <ChildContent2><div>@person.LastName</div></ChildContent2>
</Repeater>
```

The parameter name can be overridden by using the `Context` parameter on the child content element:

 ```
<MyComponent Items="People" Context="person">
    <ChildContent1 Context="item"><div>@item.FirstName</div></ChildContent1>
    <ChildContent2><div>@person.LastName</div></ChildContent2>
</Repeater>
```

If the component defines a `Context` parameter already then we won't synthesize one - your component's parameter will work exactly as it did before this feature.
