Subject: [PATCH] QPdfWriter: fix embedding fonts in pdf files

The container size change from int32_t to int64_t created a subtle error
during font serialization. The size of a QByteArray was serialized
without a proper cast and therefore now 8 bytes instead 4 bytes were
written to the stream.

Fixes: QTBUG-89727
