Recording this metadata once avoids the need to open the PDF document every time we enter scanQueue. Signed-off-by: Jared Van Bortel <[email protected]>

I was able to confirm that for large PDFs with many high-resolution images, the open for reading metadata can reliably take more than 100ms, which before this PR would prevent any words from being read. Before (current main): Before the docx change, we would always read at least one page, even if it meant exceeding 100ms. After (this PR): |

It has been brought to my attention that some users are still experiencing hangs in LocalDocs indexing after v3.4.1 that they did not see in v3.3.x or earlier. This is likely a result of #2986. Although the duration timer itself has been in #2396 without much issue, before we would at least process one page of a PDF if beginning the transaction took just under 100ms. Now we may not even process a single word.
I've now realized that the QPdfDocument we use to get metadata may also contribute to this, which this PR doesn't entirely fix - we may still only get a single word per iteration.
TODO: This should be changed such that we do not need to open the PDF document every iteration.Done.Checklist
