Support SvelteKit SDK Setup

[Lms24]

The Sentry Wizard should support setting up the SvelteKit SDK, similarly to setting up the NextJS SDK.

### Tasks

Removed the last task of wrapping load functions in favour of doing this at build time. We're not going to add a wizard-based solution at this time, as we're still waiting on a handleLoad hook for the final solution. The interim solution will be a build-time based auto-instrumentation similar to what we're doing in the NextJs SDK.
