Remove deprecated `_experiments.androidProfilingOptions` in v9

## Summary

The `_experiments.androidProfilingOptions` option was deprecated in favor of `_experiments.profilingOptions` in #5611 (2026-02). Its JSDoc already states it "will be removed in the next major version." Fallback code currently resolves `profilingOptions ?? androidProfilingOptions` for backwards compatibility.

Per the [SDK Deprecation Lifecycle Standard](https://develop.sentry.dev/sdk/), this should be removed in the next major (v9).

## Action for v9

- `packages/core/src/js/options.ts` (~line 499): remove the `androidProfilingOptions` type definition from the `_experiments` block.
- `packages/core/src/js/client.ts` (~line 255): drop the `?? this._options._experiments?.androidProfilingOptions` fallback.
- `packages/core/src/js/wrapper.ts` (~lines 67, 309, 316-317): remove the `androidProfilingOptions` parameter and the `profilingOptions ?? androidProfilingOptions` compat resolution.
- Update/adjust any related tests.

Start with the listed locations in packages/core/src/js/options.ts, client.ts, and wrapper.ts, then inspect related tests for androidProfilingOptions and profilingOptions. Confirm the deprecated type, fallback, parameter, and compatibility resolution are removed for v9 while the replacement profilingOptions path remains covered by passing tests.
