windows: some random things

[paperclover]

• Fixes windows: bunx / bun create is not implemented #8045
• Furthers windows cannot run scripts if the environment contains invalid UTF-8 #8197, but invalid utf8 in the env will omit those variables. left a todo comment.
• Wrote the glue to allow Bun Shell in package.json scripts. It is not enabled by default but only if you use --no-native-shell. Once zacks shell branch is merge we will flip to --native-shell to opt out of this behavior.
• Fix running bin files that are three or less characters.
