fdo#76356 : Docx file contianing chart in footer/header gets corrupted.

-  Docx file with chart in footer/header or .bin file referred in chart
was getting corrupted.
-  Embedded file for footer.xml was not grabbaged.
-  .bin embedded files were not grab baged.
-  Added grab bag support for both case.
-  Added UT to check .bin files are grab baged properly.
