Stop using git for the version tag.
The new process is as follows:
1. The `VERSION` file contains the version.
For release, it should contain "1.5.0".
Immediately after the release, it should be changed to "1.6.0-dev".
2. The build type is included in the version string unless it is
"Release". The commit hash is now included into the version string
whenever the `VERSION` file has a suffix (i.e. 1.5.0-dev rather than
just 1.5.0). The full version string for development builds now
looks like this: `1.5.0-dev-Debug-b102dccf8`.
This means we longer need git or `-DVERSION_NUM` to get a sensible version number.
The in-development versions are now always clearly indicated with the
`-dev` suffix no matter how DevilutionX was built.
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
libmpq is a much simpler alternative to StormLib for reading MPQ archives.
We use our own fork of libmpq: https://github.com/diasurgical/libmpq
Impact:
* DevilutionX is now a lot more portable. Unlike StormLib, libmpq only
needs platform-specific code for Windows.
* Locks around file access **removed** (instead we duplicate the file descriptor for streamed audio only).
* RAM usage is **300 KiB** lower than StormLib.
* Stripped release linux_x86_64 binary is **32 KiB** smaller.
* Amiga build now hangs instead of crashing.
