Add libwvdrmmediacrypto_hal_test for AIDL service.

[ Merge from http://go/wvgerrit/151349 ]

- move plugin and mCdm creation in SetUp() test fixture
- replace StrictMock<MockCD<> with NiceMock; otherwise,
  "uninteresting mock for isOpenSession" will return fail by default
- replace .WillOnce() for isOpenSession() with .WillRepeatedly

Test: m libwvdrmmediacrypto_hal_test -j128
Test: m libwvdrmmediacrypto_hal_test  WV_UNITTESTS_BUILD_TARGET=hidl -j128

Test: adb shell  LD_LIBRARY_PATH=/vendor/lib64
