Add third party libraries necessary for Android databinding.

[ahumesky]

1. Updates databinding to 3.4.0
2. Updates gson to 2.8.0
3. All other libraries are added:

third_party/animal_sniffer/animal-sniffer-annotations-1.14.jar
third_party/apache_commons_codec/commons-codec-1.10.jar
third_party/java/j2objc-annotations/j2objc-annotations-1.1.jar
third_party/javax_activation/javax.activation-api-1.2.0.jar
third_party/jaxb/2.3.0/jaxb-api-2.3.0.jar
third_party/jaxb/2.3.0/jaxb-core-2.3.0.jar
third_party/jaxb/2.3.0/jaxb-impl-2.3.0.jar
third_party/jetbrains_annotations/annotations-13.0.jar
third_party/jetifier/jetifier-core-1.0.0-beta04.jar
third_party/juniversalchardet/juniversalchardet-1.0.3.jar
third_party/kotlin_stdlib/kotlin-stdlib-1.3.21.jar
third_party/kotlin_stdlib/kotlin-stdlib-common-1.3.21.jar
third_party/kotlin_stdlib/kotlin-stdlib-jdk7-1.3.21.jar
third_party/kotlin_stdlib/kotlin-stdlib-jdk8-1.3.21.jar

Necessary for #2694.

Note that none of the added dependencies become part of bazel: The new dependencies become part of the android remote tools, which are hosted in a separate download. The tools are just built out of bazel's repo, which is why these dependencies are being added here.

Sorry for the delay. I'm merging this now.

@ahumesky I'm getting a merge-conflict on the third_party/BUILD file. Could you please rebase this against master?
