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.
`std::make_unique<T[]>(size)` always zero-initalizes the array.
C++20 has `std::make_unique_for_overwrite` to avoid that, while
older C++ versions can use the approach applied here.

Temporary commit
`CelOutputBuffer` now contains an `SDL_Surface` and an `SDL_Rect`.
We now have access to SDL surface manipulation functions.
`gpBuffer` and `gpBufEnd` are completely gone 🧹
This results in some FPS loss (250 -> 195) recovered in a subsequent
commit.
Do not limit filesystem paths to 259 chars for MPQs, save files, and diablo.ini.
The MAX_PATH constant remains but now only limits path lengths within the MPQs.
