Transform Svelte components with svelte2tsx while mapping symbols and ranges back to the original source. Cover runes, legacy and JavaScript components, imported stores, malformed files, modern module resolution, and cross-project prop identity.

Limit direct import-alias resolution to generated Svelte sources and imports from .svelte modules so ordinary TypeScript indexes remain byte-for-byte unchanged. Amp-Thread-ID: https://ampcode.com/threads/T-01a029e2-5095-710a-9cce-0c6d8645c173

This PR implements basic support for indexing Svelte projects with this indexer as well. It uses
svelte2tsxand maps SCIP symbols and ranges back to the original.sveltesource files via the source maps.Verified against the Sourcegraph webapp, everything passes.
See the included snapshots for some example data.
This is likely not 100% perfect, but it's a solid start that we can build on more (just like scip-typescript itself).
