Convert most of the code in `Makefile` to [Magefile](https://magefile.org/):
This makes it possible to build Flamenco without `make` (and the POSIX environment/commands it expect) by running:
```bash
$ go run mage.go webappInstallDeps # Only on the first build.
$ go run mage.go build
```
More efficient builds are possible with other commands, and some release-related commands still require `make`. At least the barrier to entry should be considerably lower (compared to having to install Make + Cygwin/MSYS2 on Windows).
Fix: #102633
This does not port the building of release packages, so it doesn't address #102671.
