Bazel: Consume toolchain_java from @bazel_tools//tools/jdk package

Starting from Bazel 0.19.x toolchain_java and absolute_javabase are
exposed in Bazel's @bazel_tools//tools/jdk package. Remove our own
definition of those rules and adapt the documentation.

Test Plan:

To build with Java 11 and newer Java versions:

* To build:

  $ bazel build \
    --define=ABSOLUTE_JAVABASE=/usr/lib64/jvm/java-11 \
    --host_javabase=@bazel_tools//tools/jdk:absolute_javabase \
    --host_java_toolchain=@bazel_tools//tools/jdk:toolchain_vanilla \
    --java_toolchain=@bazel_tools//tools/jdk:toolchain_vanilla \
    :release

* To run the tests --javabase option must be passed as well:

  $ bazel test \
    --define=ABSOLUTE_JAVABASE=/usr/lib64/jvm/java-11 \
    --javabase=@bazel_tools//tools/jdk:absolute_javabase \
    --host_javabase=@bazel_tools//tools/jdk:absolute_javabase \
    --host_java_toolchain=@bazel_tools//tools/jdk:toolchain_vanilla \
    --java_toolchain=@bazel_tools//tools/jdk:toolchain_vanilla \
    //...

Alternatively, JAVA_HOME should be set to the new Java version:

  $ JAVA_HOME=/usr/lib64/jvm/java-11 bazel test \
    --define=ABSOLUTE_JAVABASE=/usr/lib64/jvm/java-11 \
    --host_javabase=@bazel_tools//tools/jdk:absolute_javabase \
    --host_java_toolchain=@bazel_tools//tools/jdk:toolchain_vanilla \
    --java_toolchain=@bazel_tools//tools/jdk:toolchain_vanilla \
    //...
