Fix unreported: Packing/unpacking errors don't mention tiled images

Thanks to @dfelinto for spotting this!

remove pad_up function

GPencil: Fix unreported missing annotation popover menu

This was introduced when annotations was splited.

Fix T73713: Tiled textures (UDIM) getting lost when saving the .blend but not the textures

The issue here is simple, IMA_SRC_TILED was missing from a check for whether the image should
be saved.

Note that tiled images won't be automatically saved if they have never been saved before.
For single images this is handled by packing them, but packing of tiled images isn't
supported yet.

However, in that case the file closing dialog will at least show a warning now instead of
completely ignoring tiled images.

Cleanup/Refactor: Move ID deletion into its own .c file.

Having functions defined in `BKE_lib_id.h` implemented into
`lib_remap.c` was confusing at best.

Besides trivial code splitting and header includes cleanup, had to add a
new `lib_intern.h` header for callbacks used by both remapping and
deletion code.

BLI: add utilities for defining non-movable and non-copyable classes

Structs and classes can subclass these member-free classes privately.
Then they become non-movable, non-copyable or both.
