Make test projects for consuming NPM libraries

[ascott18]

Make test projects for consuming NPM libraries, build tests that execute these tests, and fail the build if the tests fail.

Test cases:

• vue-cli + vuetify + coalesce-vue-vuetify
• vue-cli + vuetify/lib + coalesce-vue-vuetify/lib + unplugin-vue-components
• type: "module" + vite + vuetify + coalesce-vue-vuetify
• type: "module" + vite + vuetify/lib + coalesce-vue-vuetify/lib + unplugin-vue-components
• type: "commonjs" + vite + vuetify + coalesce-vue-vuetify
• type: "commonjs" + vite + vuetify/lib + coalesce-vue-vuetify/lib + unplugin-vue-components
