Expose $wgMaxArticleSize in siteinfo query api

Currently, an user of the api has to try to save a page to see,
if it's too big, or not. A much saner way would be, that the api user
reads the siteinfo of the target wiki to know the maximum size of a
page and trim the edit to not exceed this limit.

This commit exposes the value of the configuration variable, which
handles the maximum article size.
