Replace __OXIDE__ at build time to prevent @tailwindcss/oxide leaks in the stable engine (#10988)
* replace `env.OXIDE` with global `__OXIDE__`

This will allow us to replace the `__OXIDE__` at build time, and fully
remove the branches from the final code so that there is not even any
reference to `@tailwindcss/oxide` on the stable engine.

* update changelog

* use `env.ENGINE` in integration tests

* drop oxide branching for the PostCSS plugin for now

This is currently a redirect to the same file, so doesn't hurt.

* Enable better dead-code elimination

* Update CLI tests

Fix indentation
