Alan Screen 010c8d7ce7 Add browser test to change Print Preview paper size
Introduce a test which changes the paper size after the initial preview
has been prepared.  Changing the paper size initiates a rerender for
the new page, and causes another call to
PrintViewManagerBase::UpdatePrintSettings().  This provides a test to
cover the Windows behavior for calling UpdatePrintableArea().

Update TestPrintBackend::GetPrinterSemanticCapsAndDefaults() so that
it sets the printable area the same way as PrintBackendWin, where any
paper size other than the default paper has a printable area that
matches the physical size.

To make the test meaningful, modify the test papers by
PrintBrowserTest::AddPrinter() so that they have a printable area which
is different than the physical size.  Include matching changes to the
paper sizes used in system_access_process_print_browsertest.cc for
checking the resultant sizes in device units.

//printing contains foundational code that is used for printing. It can depend on other low-level directories like //cc/paint and //ui, but not higher level code like //components or //content. Higher level printing code should live in //components/printing or the embedder.
