BREAKING: `DENO_FUTURE=1` by default, or welcome to Deno 2.0 (#25213)

This commit effectively turns Deno into Deno 2.0.

This is done by forcing `DENO_FUTURE=1` env var, that was available in
the past few months to try Deno 2 changes.

This commit contains several breaking changes scheduled for Deno 2:
- all deprecated JavaScript APIs are not available any more, mostly
`Deno.*` APIs
- `window` global is removed
- FFI, WebGPU and FS APIs are now stable and don't require
`--unstable-*` flags
- import assertions are no longer supported
- "bring your own node modules" is enabled by default

This is the first commit in a series that are scheduled before the Deno
2 release.

Follow up work is tracked in
https://github.com/denoland/deno/issues/25241.
