[experiment] add alternative wasm sqlite3 implementation available via build-tag (#2863)

This allows for building GoToSocial with [SQLite transpiled to WASM](https://github.com/ncruces/go-sqlite3) and accessed through [Wazero](https://wazero.io/).

+//   - The instruction list is too long to enumerate in godoc.

+//   - Atomic operations are guest-only until api.Memory or otherwise expose them to host functions.
+//   - On systems without mmap available, the memory will pre-allocate to the maximum size. Many
+//     binaries will use a theroetical maximum like 4GB, so if using such a binary on a system
+//     without mmap, consider editing the binary to reduce the max size setting of memory.
