feat(Node.js): use and build for Node.js 14 by default

We're now building and deploying to the Node.js 14.x runtime by default.

BREAKING CHANGE: The default Node.js version is now 14.x. You can still use
Node.js 12.x when necessary

fix(deps): upgrade deps

fix(targets): ensure we only transpile what's necessary

before this commit we were still reading from:
- user babelrc
- user TypeScript compilerOptions (while we need different ones)
- browserlists

before this commit we were trying to minize code down to ES5 which would code
weird issues with modules like Knex:

`Class constructor  cannot be invoked without 'new'`

Which resulted in heavily transpiled code while Node.js do not need so much
changes.

It's now a lot better. Enjoy.

fix(webpack): avoid being polluted by user configuration files

feat(webpack5): move to webpack 5, +features, +fixes

fix(deps): enforce using local (local to aws-lambda-nodejs-webpack) webpack/webpack-cli
binaries
fix(deps): enforce using our local webpack & babel plugins/loaders
feat(deps): upgrade all deps
feat(deps): use webpack 5
perf(build): use webpack caching as much as possible
perf(run): use production mode of webpack
perf(size): separate and minify node_modules into vendor.js, this way you can still
possibly debug main.js in AWS console, as long as your own code is not too big
for AWS console
If you're seeing issues, let me know :)

BREAKING CHANGE: We're now using Webpack 5. If you're seeing anything weird, let
us know.
