Android: fix instrumented test compatibility and add emulator CI

[cconlon]

This PR fixes Android instrumented test compatibility issues and adds emulator-based CI testing.

• Test discovery fixes: Convert @BeforeClass + Assume pattern to @Rule pattern so tests are properly reported as skipped instead of silently dropped by AndroidJUnitRunner
• GitHub workflow: Update android_gradle.yml to run instrumented tests on emulator
• Cert path updates: Change Android cert paths from /sdcard/ to /data/local/tmp/ to avoid permission issues
• CMakeLists.txt: Update native build defines to match current wolfSSL --enable-jni configuration

Pull request overview

This PR enhances Android instrumented test compatibility by converting test discovery patterns from @BeforeClass + Assume to @Rule-based patterns, ensuring proper test reporting in AndroidJUnitRunner. It also adds emulator-based CI testing via GitHub Actions and updates certificate file paths from /sdcard/ to /data/local/tmp/ to avoid permission issues.

• Converts test availability checks from @BeforeClass methods to JUnit @Rule implementations for proper test skipping behavior
• Adds GitHub Actions workflow for running instrumented tests on Android emulator with proper certificate file setup
• Updates native build configuration in CMakeLists.txt to match current wolfSSL --enable-jni defines

• The order value Integer.MIN_VALUE + 2 is a magic number. Consider adding a comment explaining why this specific order is necessary, or define a named constant to clarify the rule ordering strategy used across test classes.
  src/test/java/com/wolfssl/wolfcrypt/test/DhTest.java:1
• The string "Key size error" is duplicated across multiple locations in this file (lines 104, 150, 202). Consider extracting this to a constant at the class level to improve maintainability.
