Remove Widevine CDM Dependency on STLPort

* Replace an stlport static assert with a C++11 static_assert.
 * Move some libraries that were being built with the NDK but
   statically included into platform code off the NDK.
 * Rebuild the obfuscated binaries to use the new STL.
 * Remove MIPS support temporarily due to an inability to generate
   obfuscated binaries for it. (To be fixed in b/19482469.)
