Closes#15159
This PR extends the `@tailwindcss/node` packages to be able to overwrite
the CSS and JS resolvers. This is necessary as some bundlers, in
particular Vite, have a custom module resolution system that can be
individually configured. E.g. in Vite it is possible to add custom
[resolver
configs](https://vite.dev/config/shared-options.html#resolve-conditions)
that is expected to be taken into account.
With the new `customCssResolver` and `customJsResolver` option, we're
able to use the Vite resolvers which take these configs into account.
## Test Plan
Tested in the playground by configuring [resolver
conditions](https://vite.dev/config/shared-options.html#resolve-conditions)
(with Vite 5.4 and Vite 6 beta). An integration test was added for both
the JS and CSS resolvers to ensure it keeps working as expected.
