Get tst_QPdfSearchModel working; check search results in rotated text

API has changed since b6dd845ec4a6bfb6b620686681e20d38a2f24101, and this
test wasn't included in CMakeLists so we haven't been running it. Now it
checks search result rectangle bounds. The new test PDFs are from the
pdfium repository https://pdfium.googlesource.com/pdfium and include
different kinds of transforms (the Tm command apparently).

Task-number: QTBUG-120764
