This change adds a new "generic" theme to the Windows implementation of

test_shell, so that we can render controls in a platform-verion-independent
manner, allowing us to use (almost) a single set of baselines for all 
versions of Windows.

test_shell is modified to accept three new switches: --ux-theme (for the
default or "new" XP/Vista theming engine), --classic-theme (for the older
"Classic" theming engine), and --generic-theme (for the new Skia-based 
test theme). Specifying --layout-tests will default to --classic-theme,
otherwise --ux-theme is the default (this is compatible with existing 
test_shell behavior). Once the new version-independent baselines are 
checked in, we will flip this behavior so --layout-tests defaults to
--generic-theme as well.

This change adds test_shell_webtheme{engine,control}.{cc,h} as Windows-only
build files, and adds documentation to webkit/api/public/win/WebThemeEngine.

It also adds a chromium-win-xp platform baseline directory (currently empty)
and modifies the layout_test/layout_package/platform_utils_win.py baseline
search path to confirm to WebKit's directory search logic (vista and win7
look just in chromium-win, but XP looks in chromium-win-xp first, followed by
chromium-win).
