Refactor to remove code coupling with Webpack

Remove using Webpack import syntax such as: `js-yaml-loader!@/..`. It's
a non-standard syntax that couples the code to Webpack.

Configure instead by specifying Webpack loader in Vue configuration
file.

Enable related ESLint rules.

Remove unused dependency `raw-loader` and refactor
`NoUnintendedInlining` test to load files using file system (dropping
webpack dependency).

Refactor to use `import type` for type imports to show the indent
clearly and satisfy failing ESLint rules.
