nativeloader: Add Reset capabilities
In the case when VM is restarted all weak references from the old VM become invalid. In such event NativeLoader needs to clear the list of classloaders from old VM. Bug: http://b/28453840 Bug: http://b/28449304 Change-Id: I2268c1e21cf940c57ddc5f0312f56b71aa702134 (cherry picked from commit be4ca3afc0636b314d676480156eb6977739dd00)
