Exporting ScopedTempDir so it can be used by webkit layout tests.

Exporting ScopedTempDir so it can be used by webkit layout tests.

Testing the LevelDB backend from the webkit unit tests requires it
create a temporary file system. In order to clean this up
(and on all platforms) we are going to make the scoped_temp_dir
functionallity available to LayoutTestController.


TEST=This is a thin wrapper on ScopedTempDir which is already covered by unit testing. This will be connected to LayoutTestController (a future patch in WebKit).

File webkit/support/webkit_support.cc (right):

http://codereview.chromium.org/7034047/diff/5001/webkit/support/webkit_suppor...
webkit/support/webkit_support.cc:499: return
tempDirectory_.path().MaybeAsASCII();
this probably isn't a big deal for developers, but this looks like it would not
work well if the temporary directory contains non-ASCII chars (can happen on
Windows).

we normally pass file paths to webkit using WebString and
webkit_glue::FilePathToWebString.
