Speed up QQmlEngine constructor
Freezing the global object using a script is pretty slow,
esp. given that the script needs to be compiled as well. Rather
do it programmatically.
The old code actually had a bug that would only cause the global
object to be frozen, not it's children. The new code fixes this,
but doesn't completely freeze the objects. Instead it makes all
the existing properties of the global object and it's children
readonly, but still allows extending existing objects with new
properties.
