FPDF_ImportNPagesToOne function is added to support N-up feature
for print.
If numPagesOnXAxis * numPagesOnYAxis == 0
Returns a nullptr.
If numPagesOnXAxis * numPagesOnYAxis == 1
Creates a new PDF document, and import one page to each output
page of the PDF document
If numPagesOnXAxis * numPagesOnYAxis > 1,
FPDF_ImportNPagesToOne imports multiple pages onto the same page.
This feature is intended for print pipeline to use.

This CL adds helper methods for EmbedderTest to save. This means that
TestSaver is no longer needed and all the methods it uses are moved to
the EmbedderTest.

It's possible to create a stream of length 0 in a PDF document.
Currently the code will early exit and return a nullptr. This causes
issues when you want to print the given PDF as the FPDF_ImportPages code
ends up only generating up to the zero length object.
This CL allows creating streams with length 0 and updates the PDF saving
code to output a blank stream.

CloneNonCycle() tries to detect cyclic object references without copying
them. There are two issues:
-- for elements in an array or a dictionary, they should be able to
refer to the same object, which are not cyclic;
-- for cyclic referenced elements in an array or a dictionary, do not
clone the element at all. Having nullptr or <key, nullptr> as an element,
like we did before, might cause crash when the element being accessed.

There's a path out that deletes a pointer whose ownership
was passed off earlier. This will get simpler once more
APIs take unique_ptr.

The lack of coverage of the fpdfppo APIs was noticed while
trying to diagnose another issue. Adding basic calls to
these APIs then kicked out an assert in XFA, where duplicate
global CFXA_TimeZoneProviders were not expected. These are
cheap to create except for the global C RTL tzset() call, so
keep track of that and make these on demand.
