Load native GLES driver when specified.

Since ANGLE and native GLES drivers can coexist, when native is
specified, the loader must load the native GLES drivers specified in
ro.hardware.egl. This patch passes this information down to the native
graphics environment so that the EGL loader can properly check.

Bug: b/283858001
Test: atest CtsAngleDeveloperOptionHostTest -c with ANGLE being default
Test: atest CtsAngleDeveloperOptionHostTest -c with native being default
