Remove dependency to libmediadrm from drm HAL
drm HAL has been using libmediadrm for android::SharedLibrary class and
android::PluginLoader class. This is a Treble violation since
libmediadrm is a framework-only library that is not available to
vendors.
To solve the problem, the two classes are copied into this directory
to form a small static library android.hardware.drm@1.0-helper.a.
