Mark libEGL, GLESv1_CM, GLESv2, and GLESv3 as LLNDK

They are used by libRSDriver and libRS_internal which are VNDK-SP
libraries. Therefore, the EGL/GLES libs must be LLNDK or VNDK-SP. We
choose to make them as LLNDK since they already have stable ABIs (as
they are NDK).

In addition, two more functions of libEGL are exposed to vendors

eglQueryStringImplementationANDROID and eglDupNativeFenceFDANDROID are
non-NDK symbols but are being used by libgui, which is a library marked
with vendor_available:true. In order to provide the symbols to the
library, they are added to the map.txt file and tagged as "# vndk" so
that they are exposed only when built for vendor libs (and hidden when
built for NDK).

Furthermore, eglQueryStringImplementationANDROID is changed to C-symbol
in order to be mentioned in the map.txt file, where C++ mangled symbol
name can't be used.
