[Service][Global] Expose standard and global objects

This enables functions and properties of global object,
such as setInterval, setTimeout, and etc in service apps.

Also, the primitives and standard objects are exposed
to fix following undefined and type-mismatched errors:

> Cannot set property 'setDate' of undefined
> Cannot convert 11,21,31,71,81,91 to Uint8Array
