This PR don't really provide d8 support, but exports two additional properties available inside AndroidBuilder methods:

• this.androidInfo.sdk.d8 - path to d8 jar
• this.tiapp.android.enableDesugar - value of property in tiapp.xml:

<ti:app xmlns:ti="http://ti.appcelerator.org">
  ...
  <android>
    <manifest>...</manifest>
    <enableDesugar>true</enableDesugar>
  </android>
  ...
</ti>

P.S. Origin of enableDesugar property name.

This D8 option is really important, we are having the same issues with the last JWPlayer (which uses Exoplayer). And more libraries are starting to use some Java 8 features.

The patch is working great for us, thanks for the workaround because the new JWPlayer libraries update were really blocking our apps.

Closing, as we will be using D8 through moving to Gradle builds.
