Dulmandakh 38eb2a70af Enable Java8 (#23295)
Summary:
Running *lint* on RN found that there are some Java 8 features used without specifying Java 8 compatibility in projects. This PR adds Java 8 compatibility and fixes errors caused by Java 8 feature use. I suspend that it may be cause of many failures on older Androids, but also found that many modules/packages switched to and require Java 8.

```java
../../src/main/java/com/facebook/react/devsupport/BundleDownloader.java:167: Try-with-resources requires API level 19 (current min is 16)
../../src/main/java/com/facebook/react/devsupport/DevServerHelper.java:658: Try-with-resources requires API level 19 (current min is 16)
```
