Remove denort optimization (#10350)

denort is an optimization to "deno compile" to produce slightly smaller
output. It's a decent idea, but causes a lot of negative side-effects:

- Deno's link time is a source of constant agony both locally and in CI,
  denort doubles link time.
- The release process is a long and arduous undertaking with many manual
  steps. denort necessitates an additional manual zip + upload from M1
  apple computers.
- The "deno compile" interface is complicated with the "--lite" option.
  This is confusing for uses ("why wouldn't you want lite?").

The benefits of this feature do not outweigh the negatives. We must find
a different approach to optimizing "deno compile" output.
