Bugfix: two bugs related to pasting image data into krita, along with some refactoring ( BUG: 475409 )
This fixes "Paste into active layer" with non-krita mime type image sources (which seems to me was completely defunct), and also fixes wonky math around detecting when a pasted image is outside of the bounds of the canvas its being pasted into.
There is also some minor refactoring of the affected code.
Edit: seems like i also inadvertedly fixed a use-after-free and double free combo, heh.

Test Plan
- make a new biggish image A
- draw a blob in the top left and bottom right corners of image A
- select and copy:
- the top left blob in image A
- the bottom right blob in image A
- both blobs and the space inbetween them
- both blobs without the space inbetween them
- any image in another image processing application
- create a second image B, much smaller in size
- paste:
- "paste into active layer" on image B
- regular paste on image B
- ensure the paste worked correctly. for 3c and 3d you may not see anything, but the transform should be centered on the image and the too guides visible
