Update webkit_resources to support high-dpi assets

Update webkit_resources to support high-dpi assets

Move webkit_resource.grd to be in the same directory as all the resources.
This is consistent with what we do elsewhere, and avoids a limitation of the
new grit support for chrome_scaled_image (it expects 'context' to be a specific
form).

Move all the current images into a default_100_percent sub-directory.
Images were added to their new location separately (due to try/cq limitations 
on binary files) here: http://src.chromium.org/viewvc/chrome?view=rev&revision=148389

Add support for the 2x text area resize corner image.

Note that I didn't make the .cur files support multiple resolutions because
.cur files themselves can contain multiple resolutions, and when we support
high-DPI on windows (the only place these are used), we'll probably want to
use multi-resolution .cur files so that the cursor seamlessly changes when 
moving between different density screens.

Also fixes the addition of 'hand' cursors to be windows specific (as all the other 
cursors are now).

Brett, can you please review this change?  You're an OWNER for most of the
directories, and it's related to your recent hand cursor addition.

Sky for OWNERS in ui/ only (trivial).

Ping.

I'm a bit confused, I see a bunch of deleted resources but don't see where they
moved to.

[brettw, 2012-07-27 20:47:53]

Oh, I missed the comment, nevermind.

[brettw, 2012-07-27 20:54:27]

The code is fine as far as I can understand it :)

Thanks Brett.

Sky, can I please get your OWNERs review for the couple tiny changes in UI?

TBRing Sky - he's swamped and the piece in ui/ is trivial and follows directly
from the rest of this CL (lists PAK files to load), it's really not worth
harassing him for this.  Plus it's about to be replaced any day now so we don't
have to keep updating this list when we add a new pak file
(http://crbug.com/139803).

Do you need to change resource_bundle_Mac.mm too?

Whoops, thanks.  Not sure how I missed the Mac case.  This will all be
simplified shortly by flackr@'s change, but I should make this CL complete by
itself anyway.  Done.
