Avoid fatal OOM in CStretchEngine::StartStretchHorz().

Before https://pdfium-review.googlesource.com/100310, StartStretchHorz()
was a bit too conservative with its memory allocation limit and failed
for some legitimate use cases where PDFium had enough memory. Now, that
limit has been lifted and sometimes PDFium tries to allocate too much
memory. Instead of making this fatal, fail gracefully by switching from
DataVector to FixedTryAllocZeroedDataVector.
