SVG export: try to reuse original bitmap data for JPG and PNG bitmaps
This has a number of benefits:
1) For a sample JPG photo, the SVG output is now 4,9MB, not 20MB.
2) Even the first export to SVG is fast, see commit
570be56b37e4ff105649e604ff4c8a6c368e2e79 (svx: cache PNG export of
graphic shapes, 2020-02-25) for exact numbers.
3) Allow using less memory as the SdrGrafObj doesn't have to store a PNG
result till the document is closed.
We still require matching checksums, so in case anything problematic
happens with the bitmap (grayscale filter applied, etc), then the
optimization is meant to not help, but still produces correct output.
