qdev-properties: add getter for size32 and blocksize

Add getter for size32, and use it for blocksize, too.

In its human-readable branch, it reports approximate size in
human-readable units next to the exact byte value, like the getter for
64bit size does.

Adjust the expected test output accordingly.
