Normalize user provided URL link for Special:LinkSearch page

Using Parser::normalizeLinkUrl() to normalize links before passing them to
the Special:LinkSearch handler allows us to avoid URL encoding issues when
searching for URL with special/escaped characters.
E.g. As listed in T126913 currently user needs to provide URL exactly as it
is stored in MediaWiki (' vs %27) in order to find it.
Normalizing URL will allow searching in Special:LinkSearch page using both
direct and encoded characters (since it will get normalized to the uniform
format).
