transformer: untangle `@oxc-project/runtime` version from the transformer version

[sapphi-red]

Currently @oxc-project/runtime's version is synced with the transformer's version. This has some downsides:

1. the user need to sync the version of @oxc-project/runtime and oxc-transform
2. the runtime helper is bundled multiple times when a user uses multiple libraries that used different versions of oxc to transform the code

By untangling these (i.e. having a separate version for @oxc-project/runtime), we can solve these downsides.

1. @oxc-project/runtime version will not be bumped frequently so it'd be easier to bump oxc-transform version (and Rolldown / tsdown version)
2. Since @oxc-project/runtime 1.1.x will be compatible with 1.0.x, a single 1.1.x can be bundled inside of multilpe versions.

That said, there's one problem with doing this. Bumping the required @oxc-project/runtime version in oxc-transform is technically a breaking change. I guess that is fine as that's the way tslib (TypeScript) handles. Babel handles this by inlining the missing newer helper functions if the installed helper package does not have them.
