*Fixup about and chrome scheme URLs in URLFixerUpper::FixupURL.

*Update AboutSource to use the source_name of each about/chrome page.
*Make WillHandleBrowserAboutURL fix up schemes and handle chrome://foo/
-Redirect memory to memory-redirect (wasn't handling chrome://memory/).
-Catalog all kChromeUI*Hosts in url_constants.cc
-Simplify paths (credits, os-credits, ipc, settings, about/version).
-Nix web_ui_util::ChromeURLHostEquals (use scheme & host comparison).
-Favor GURL::SchemeIs and url_constants, update & expand tests.
-Add and fixup chrome://chrome-urls (the about:about page).
-Update special_tabs.py from Nirnimesh's codereview.chromium.org/6995057/.

This change was reverted with r88166 for sync_integration_tests failures.
These failures are a tangential issue, crbug.com/85294; I'll re-land this soon.

BUG=55771
TEST=Access about:, about://, chrome:, chrome:// pages.
