Summary:
The original proguard rules are put in the template, which is not very convenient and easy to get wrong. Because new rules get put, people also has two copy paste the rule. And there are also existing project import react native as a dependency. So the best way to keep a android library project proguard rule is to manage the rule itself, using `consumerProguardFiles` like [dagger](46baef6d96/butterknife/build.gradle (L9)) and other android library project.

Use RNTester to build the release flavor (now it has bugs https://github.com/facebook/react-native/issues/18460, I keep my change in local for now), after build success, run to check if crash.
In the process, I also fix https://github.com/facebook/react-native/issues/12994 and https://github.com/facebook/react-native/issues/6624 by adding the following to proguard rules
```proguard
-keep,includedescriptorclasses class com.facebook.react.bridge.** { *; }
```

Summary:
This PR enables obfuscation in ProGuard by default when creating a new project, and documents how developers can turn obfuscation off if they desire.
The ProGuard phase is currently disabled by default. If a developer wanted to enable ProGuard, the first thing they would see is the following line in their build.gradle file: `def enableProguardInReleaseBuilds = false`
It's really easy to assume that enabling this flag will setup code shrinking and obfuscation, as this is the default behaviour for a completely native Android Studio project, or when running ProGuard from the command line directly.
However, the generated ProGuard rules override the default behaviour. Without visually inspecting the rules file, searching for a mapping file, or analyzing the Dex file classes, this isn't immediately obvious, as the APK will be smaller, and gradle will show the Proguard task as completing.
Personally I find this confusing and really wasn't expecting for obfuscation to be disabled - most Android Error Reporting services allow deobfuscation of stacktraces via mapping files.
1. Create a new project using `react-native init MyProject`
2. Observe that `-dontobfuscate` is commented out

Summary:
This is the manually imported version of https://github.com/facebook/react-native/pull/10786
This was mostly straigthforward by replacing the local-cli folder with the version I had in my local git checkout,
plus a few other files I listed with git diff --name-only.
