LPS-34069 handle table and pre tags

JavadocFormatter updated to leave table and pre content as-is.

Updated Javadoc in source files as follows ... Flattened <table> related tags as we do with other nested tags. Leave <table> and <pre> contents un-formatted. Wrap tables and preformatted content in <p> tags to space them out from Javadoc content on lines above and below.
