Updates prior to cutting over chrome.dll to gyp generation:...

Updates prior to cutting over chrome.dll to gyp generation:
* Add dependency on the 'theme_dll' target, commented out
  to avoid a problem with default.lib not being generated.
* Make the location of the generated chrome_dll_version.rc file consistent
  with other uses of SHARED_INTERMEDIATE_DIR.
* Add the necessary generated *_resources.rc to 'sources'.
* Remove 'process_outputs_as_sources' from the 'chrome_dll_version'
  action.  It's now that it's in its own target.
* Add settings from chrome\app\chrome_dll.vsprops.

This doesn't convert chrome.dll to gyp generation.  There's still some setting
or dependency issue that's getting in the way.  This CL just clears out a number
of configuration items that are necessary to build chrome.dll in a fashion
similar to the currently checked-in VS files, so that (I hope) I can better spot
whatever difference still needs to be accounted for.

Updated.  Commented out the theme_dll dependency because it causes the same
problem with default.lib not being generated.  Added settings from
chrome\app\chrome_dll.vsprops.  msvs_existing_vcproj still points to the
checked-in chrome\app\chrome_dll.vcproj, so
