ASA Go: Android tests and coverage uploads

[conbrad]

• Extract repeated Node.js/keycloak/asa-go setup into a shared composite action (.github/actions/asa-go-setup)
• Restructure integration workflow into three parallel jobs: js_test, ios_test, android_test
• Add JaCoCo coverage to Android (asa-go and keycloak plugins) and upload all coverage (JS, iOS .xcresult, Android XML) to Codecov with
  per-platform flags
• Update mobile/asa-go/README.md with correct local build order (keycloak first), platform-specific cap sync, and CI workflow documentation

Closes #5182

There's still some things to sort out with codecov. I tried carrying forward asa-go tests in codecov.yml, which kind of worked but PRs don't always reference the coverage in the 'flags' section for some reason

https://app.codecov.io/gh/bcgov/wps/flags

I think all asa-go tests need to be carried forward because they aren't run on every PR
