Set `oxc: false` for rolldown-vite

[sapphi-red]

Clear and concise description of the problem

This plugin sets esbuild: false for Vite.

unplugin-swc/src/index.ts

Line 110 in dfc3ce4

esbuild: false,

But since rolldown-vite uses Oxc (and has a different behavior) esbuild: false does not have effect.

Suggested solution

Set oxc: false for rolldown-vite. Probably that's most people would expect.

Alternative
