Description

Add back removed test for SqlCipher loader

Steps to test this PR

QA-optional

---

Note

Low Risk
Low risk: only unit test and Gradle test configuration changes, no production logic modifications. Main risk is potential test flakiness or slower test execution due to added Robolectric resources.

Overview
Adds a Robolectric-based test suite for RealSqlCipherLoader.waitForLibraryLoad, covering success, load failure, timeout handling, cancellation propagation, single-initialization behavior, concurrent callers, and early-load triggers via onCreate/onPirProcessCreated.

Updates sqlcipher-loader-impl test setup to support these cases by adding Robolectric/AndroidX test dependencies, enabling includeAndroidResources, and introducing a ShadowLibraryLoader to simulate native library load callbacks without loading real binaries.
