Revert of Input type url with line break and leading-trailing whitespace should be stripped.

Revert of Input type url with line break and leading-trailing whitespace should be stripped. (patchset #2 id:20001 of https://codereview.chromium.org/836113002/)

Reason for revert:
Reverting this Patch, as this will break the old behavior of browser in case of user types spaces into input box type url.

It need to be discussed with wider audience, what should be the correct behavior in case of user inputting and JavaScript setting the input value, to reland this patch.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer,
_not_ a full super star committer.

Note that this has nothing to do with OWNERS files.
