[Feature Request] Add `nuxt/prefer-nuxt-link` rule

[laizp]

Describe the feature

As <NuxtLInk> could handle any kind of links, there is a reason to use <NuxtLink> as a unified form of linking instead of mixing <NuxtLink> and <a> tags. So we can add a nuxt/prefer-nuxt-link rule to restrict the use of the <a> tags.
