Use node package dependency to manage JSC version (#24276)

Summary:
In origin approach, we packed libjsc.so inside react-native.aar and it is difficult for user to choose different JSC variants. E.g., [the Intl supported version](https://github.com/react-native-community/jsc-android-buildscripts#international-variant).

This change list allows application to determine JSC versions or variants by npm/yarn package.

There is a |useIntlJsc| flag in build.gradle, it will use the same JSC version but with Intl support.

`yarn add jsc-android@canary`

[Android] [Changed] - Allow application to select different JSC variants

**MIGRATION**
Note that there are some changes in build.gradle.
Existing application needs to change their android/build.gradle and android/app/build.gradle.
Hopefully, the rn-diff-purge should handle the case well.
