Download artifacts from CI to speed up testing (facebook#37971)

Summary:
Testing releases takes a lot of time because we have to build locally several configurations.
However, the artifacts that we build locally are also built in CI.

The goal of this PR is to implement a mechanism to download those artifacts from the CI instead of build locally, so that testing the release locally can take much less time.

As an example, the full test cycle can take more than 2 hours given that we need to repackage and rebuilt the app from the template.

My plan is to add a table with the time saved once the PR is done

### TODO:
- [x] Download Hermes tarball for RNTester iOS
- [x] Download Hermes APK for RNTester Android
- [x] Download JSC APK for RNTester Android
- [x] Download Packaged version of React Native to create a new app
- [x] Use the downloaded React Native to initialize an app from the template
- [x] Download Maven Local prebuilt in CI and use it for Template Android app

### Time Savings

| Setup | Before [s] | After [s] | Notes |
| --- | --- | --- | --- |
| iOS RNTester Hermes | 339.68 | 194.86 | Time saved by downloading Hermes rather then building it |
| iOS RNTester JSC | 129.80 | 123.35 | Not significant, expected as this workflow did not change
| Android RNTester Hermes | 1188.82 | 5.28 | Huge improvement: we download the APK rather then build |
| Android RNTester JSC | 103.10  | 6.28 | Huge improvement: we download the APK rather then build  |
| Creating the RNTestProject | 2074.82  | 191.16 | We download Maven, the packaged version of RN and Hermes instead of building from scratch |
