Turns out the squashfs mount has some non-trivial RAM overhead.
Copy the game to local storage and run from there to avoid the overhead.
This completely eliminates long 0 FPS periods when running the demo for PGO.
It may be possible to reduce the overhead by setting
CONFIG_SQUASHFS_FRAGMENT_CACHE_SIZE kernel setting to 1.
Also added an iterator based API, though it's not useful for this use-case. Might be nice in the future?
The field/record iterators is single-pass input iterators with shared state.
To avoid rescanning fields unnecessarily parseInt currently can only be called once, it would be possible to make these iterators bidirectional with a bit of extra state (holding onto the start pointer)

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. Creates the missing `shared-dl` directory.
2. Unsets some environment variables that interfere with buildroot.
3. Disables `BR2_PER_PACKAGE_DIRECTORIES`, which prevented us
from using the partial sysroot build.
Also documents the `TOOLCHAIN=...` option in docs/building.md.
With this, we no longer require `std::filesystem` support to create the
save file directory when it does not exist.
Note that by default the save file directory exists because it is
created by SDL, so this is mostly useful on platforms that override the
save directory or use `UNPACKED_SAVES`.
