all: remove support for stage1

Browse source 
With almost all tests/examples working on all platforms now with the new compiler,
https://github.com/hexops/mach/issues/180, it's time to remove stage1 support.

## Supported Zig version
Zig has switched to the self-hosted compiler recently. This is a huge milestone, but currently means that Zig nightly versions are a little bit unstable. For now, we suggest using a slightly older Zig version before the switch to the self-hosted compiler.
Mach works with the new self-hosted Zig compiler only. This means you'll need to use the latest Zig nightly version.
Currently tested with: 0.10.0-dev.3952+9e070b653
You can download binary releases of this version at:
Currently we test using `0.10.0-dev.3952+9e070b653`. Newer is generally better, but you can download this version here:
* **linux-x86_64**: https://ziglang.org/builds/zig-linux-x86_64-0.10.0-dev.3952+9e070b653.tar.xz)
* **windows-x86_64**: https://ziglang.org/builds/zig-windows-x86_64-0.10.0-dev.3952+9e070b653.zip
* **macos-x86_64** (Intel): https://ziglang.org/builds/zig-macos-x86_64-0.10.0-dev.3952+9e070b653.tar.xz
* **macos-aarch64** (Apple Silicon): https://ziglang.org/builds/zig-macos-aarch64-0.10.0-dev.3952+9e070b653.tar.xz
You can subscribe to [issue #180](https://github.com/hexops/mach/issues/180) for how we're tracking towards support for the latest nightly version of Zig.
`mach/ecs` and WebAssembly examples have known issues unless using `-fstage1`, see [issue #180](https://github.com/hexops/mach/issues/180) for details.
