HIDL interface.

Test: Play Movies (streaming and offline playback)

Test: ANDROID_BUILD_TOP= ./android-gts/tools/gts-tradefed
run gts -m GtsMediaTestCases

Test:
adb shell /system/bin/libwvdrmengine_hidl_test

Test:
adb shell /system/bin/libwvdrmmediacrypto_hidl_test

Test:
adb shell /system/bin/libwvdrmdrmplugin_hidl_test
