vcl: improve accounting of SVG images in graphics cache
The problem is that the graphics cache only counts the size of the SVG
text, which is stored in SvgData::maSvgDataArray. However the
SvgData::maSequence may use a lot more memory, as it may contain
de-compressed bitmaps that are stored as base64-encoded PNGs in the SVG
text.
For example icon-themes/galaxy/brand/flat_logo.svg is 812 Ko but contains
60 Mo of bitmaps.
This may cause excessive memory usage and failure to export documents
due to OOM; according to valgrind massif, the bitmap buffers use 90% of
the heap.
Add a new interface com::sun::star::util::XAccounting, and implement
it in drawinglayer BasePrimitive2D. VCL SvgData can't access
drawinglayer via C++ directly so this looks like the best approach.
