fix(web): generate .swcrc file with modern defaults when creating new webapps

[jaysoo]

Currently, when generating a new webapp (i.e. nx g @nx/web:app myapp), we create a .babelrc file instead of .swcrc. This makes customizing the build confusing.

This PR adds the .swcrc file when generating a new app, and also sets target to es2016 since modern browsers do not need ES5 to work. Also updated the .swcrc file for React apps to set the target to es2016 as well (which matches how our babel config targets esnext).
