chore: consolidate noop function usage across framework packages (#9228)

Multiple framework-specific packages (`solid-query`, `svelte-query`, and `angular-query-experimental`) were maintaining their own implementations of the `noop` function, creating unnecessary code duplication across the codebase.

```typescript
// Before: Each package had its own noop
// packages/svelte-query/src/utils.ts
export function noop(): void {}

// packages/solid-query/src/utils.ts (missing, causing import errors)
// Local noop definitions scattered across files
```

Consolidated all `noop` usage to import from the canonical implementation in `@tanstack/query-core`, which all framework packages already depend on.

```typescript
// After: Single source of truth
import { noop } from '@tanstack/query-core'
```

- **Removed duplicate `noop` definition** from `packages/svelte-query/src/utils.ts`
- **Updated import statements** in Solid Query and Svelte Query to use `noop` from `@tanstack/query-core`
- **Fixed missing utils file** in Solid Query that was causing import errors
- **Resolved TypeScript compatibility** issues with `noop`'s overloaded return types

- **Persisters were intentionally left unchanged** as they don't import `query-core` and maintain their own lightweight utils
- **Framework packages already depend on `query-core`**, making this consolidation natural and dependency-free
