feat(core): support rollup.config.ts (#28240)

I would like to be able to use rollup.config.ts. Same way it's used by
rollup and vite teams too.

## Current Behavior

Currently nx plugin does not reconize project containing
rollup.config.ts. It expects only {c|m}js files

## Expected Behavior
When project has rollup.config.ts rollup plugin infers build target
automatically. This build target should be able to find the
rollup.config.ts. For that purpose a special [configPlugin
](https://rollupjs.org/command-line-interface/#configplugin-plugin)CLI
parameter should be used

## Related Issue(s)
