build: require --without-debugger explicitly

* To fix nodejs#12758, added an assertion that if
  `--without-ssl` or `--without-intl` are set, --without-debugger must
  also be explicitly set.

* Added `--without-debugger` is an alias to `--without-inspector`, since
  we removed the old TCP `debug` protocol the V8 `inspect` protocol is the
  only debugger available. Hence disabling `inspector` means disabling
  any kind on JS debugger.

Fixes: nodejs#12758
