MDX integration v3 (#10935)

* fix(mdx): convert remark-images-to-component plugin to a rehype plugin (#10697)

* Remove fs read for MDX transform (#10866)

* Tag MDX component for faster checks when rendering (#10864)

* Use unified plugin only for MDX transform (#10869)

* Only traverse children and handle mdxJsxTextElement when optimizing (#10885)

* Rename to `optimize.ignoreComponentNames` in MDX (#10884)

* Allow remark/rehype plugins added after mdx to work (#10877)

* Improve MDX optimize with sibling nodes (#10887)

* Improve types in rehype-optimize-static.ts

* Rename `ignoreComponentNames` to `ignoreElementNames`

I think this better reflects what it's actually doing

* Simplify plain MDX nodes in optimize option (#10934)

* Format code

* Minimize diff changes

* Update .changeset/slimy-cobras-end.md
