feat: use type=module in (most) generated projects #158
Description
With the exception of Nighwatch templates due to nightwatchjs/nightwatch#3959
Closes vuejs/create-vue#389
Largely inspired by @cexbrayat's work in that PR.
I've also made the generation of the root tsconfig.json programmatic
because it's becoming more and more convoluted.
