feat(cli): support generation of sass and less files

[christian-bromann]

What is the current behavior?

This feature was requested in #2155 but the community PR (https://github.com/ionic-team/stencil/pull/2334) was never reviewed. Let's get this in as it seems generally useful.

What is the new behavior?

We recognise the Less or Sass plugin now, if it exists and generate a proper style file. In case Sass is used, we also ask which format they want to use (.sass vs scss files).

--strictNullChecks error report

Typechecking with --strictNullChecks resulted in 1079 errors on this branch.

Unfortunately, it looks like that's an increase of 2 over main 😞.

Violations Not on `main` (may be more than the count above)

Unused exports report

There are 15 unused exports on this PR. That's the same number of errors on main, so at least we're not creating new ones!
