Please review a change to remove incidental whitespace commonly found at the
beginning of `<pre><code>` or `<pre>{@code` tags. This patch is dependent on
[JDK-8352249](https://bugs.openjdk.org/browse/JDK-8352249) and completes the
removal of incidental whitespace in traditional doc comments.
This is implemented by parsing content of `<pre>` elements into a separate list
buffer in `DocCommentParser`, and filter the content for leading blank linkes
when the element is closed. The decision to filter `<pre>` element contents
only once the element is closed was made in order to be able to keep the logic
in a single method without further complicating other parts of
`DocCommentParser`.
