#120997 Refactor: Blend file reading asserts for broken pointers

Delete Branch "brecht/blender:refactor-typed-read"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
This makes the read and write API functions match more closely, and adds
asserts to check that the data size is as expected.
There are still a few places remaining that use
BLO_read_data_addressand similar generic functions, these should eventually be replaced as well.
See
BLO_read_write.hhandreadfile.cfor the main changes.The rest is using the new API functions throughout the code.

In general this change in the public readfile API makes sense to me, it's definitively better to allign it with the writefile code, and having the type info available is a good thing for the future. And it improves the readability of the data reading code.
Not really convinced with the assert on struct size tbh, this will only catch a small subset of the potential issues, and completely miss any case where the given type size is smaller than the actually read one. But it should not hurt either, and as discussed with @brecht IRL, improvement (like some form of RTTI check) can easily be added later if needed.
