zig0_airgen_options: restrict what can be configured

Browse Source 
1. `dev == .bootstrap` does not include wasm backend, no use.
2. different optimize modes _of the compiler_ (_not_ target) _should_
   not emit a different AIR. Thus if we want to `zig build test-zig0
   -Doptimize=ReleaseFast`, we most often mean to compile the test
   executable under this mode, but not `air_gen`, which will only emit
   the AIR for comparison.
