feat(js): allow root js lib project to be generated

[jaysoo]

The rootProject: true option for @nx/js:lib doesn't actually work. Main two problems are:

1. tsconfig.base.json is still generated even if no other projects are present to require it.
2. nx build will fail if @nx/js:swc is used because it doesn't work when the project is at the root ..
3. Choosing bundler that isn't esbuild or rollup did not install @types/node package, which is required to build libs.
