Makes `CelSprite` unowned and adds a new `OwnedCelSprite` class for
owned sprites.
This clarifies ownership and makes the code cleaner in a number of
places.
Additionally, because the `CelSprite` class is now tiny (1 less
pointer), we can pass it by-value instead of by-reference, removing a
pointer indirection in the rendering functions.
The gamepad cursor (inventory, spells etc) no longer relies on warping a
real mouse cursor. This should make things work better on platforms that
do not support this, like Wayland.
1. Adds a `libdevilution_so` target when tests are enabled.
2. Each test file is now a separate binary target linked against `libdevilutionx_so` (can now run tests in parallel).
3. Tests are now defined in a separate `test/CMakeLists.txt` file.
4. Building the tests is now controlled by the standard `BUILD_TESTING` option (defined by CTest).
5. Tests are now built by default.
6. On CI, test errors are now reported.
Also:
* `.clang-format`: Enable SortIncludes in tests
* `path_test.cpp`: Fix -Wsign-compare
Disabled by default because of these known issues:
1. When clicking on inventory item, it briefly appears a bit shifted (in the wrong coordinates).
This issue can happen with software cursor as well, but is a lot more
obvious with the hardware cursor.
2. Cursor is scaled with nearest-neighbour scaling, which may look a bit different from
how the rest of the graphics are scaled.

Instead of passing the CEL sprite width when drawing, store the CEL
width at load time in the new `CelSprite` struct.
Implemented for most sprites except towners, missiles, or monsters.
- Add file documentation to about 1/4 of the files in Source
- Copy over a lot of the documentation from the sanctuary/notes repo
- Standardise all the existing documentation
- Create a configuration for Doxygen
- Add more documentation (engine.cpp is now fully documented)
