Move NewPP limit report HTML comments to JS variables
* Instead of having messy code to create a hidden HTML
comment of English strings at the bottom of the page,
expose the structured data of the parse information
to JS so tools can use it.
* Make makeConfigSetScript() use pretty output so these
variables are also easy to read in "view source".
* Remove ParserLimitReportFormat hook, since the data
is not formatted to HTML anymore.
