feat(misc): enable new ts minimal setup by default and guard executio…

…n of generators with no support for it (#28199)

- Enable generating the new & minimal TS setup by default when
generating the `ts` preset with CNW.
The existing `NX_ADD_TS_PLUGIN` environment variable is kept with its
default value inverted and set to `true`. It can be used to opt out of
the new TS setup by running CNW with `NX_ADD_TS_PLUGIN=false`.
- Throw an error when running generators that don't yet support the new
TS setup.
- We'll add support for those generators incrementally in follow-up PRs.
