refactor(compiler): element.sourceSpan should span the outerHTML (#38581)

Browse Source 
Previously, the `sourceSpan` and `startSourceSpan` were the same
object, which meant that you had the following situation:

```
element = <div>some content</div>
sourceSpan = <div>
startSourceSpan = <div>
endSourceSpan = </div>
```

This made `sourceSpan` redundant and meant that if you
wanted a span for the whole element including its content
and closing tag, it had to be computed.

Now `sourceSpan` is separated from `startSourceSpan`
resulting in:

```
element = <div>some content</div>
sourceSpan = <div>some content</div>
startSourceSpan = <div>
endSourceSpan = </div>
```
