Add a GetEntityKeyvalue function to VScript

Describe your enhancement suggestion in more detail

As far as I’m aware, there currently isn’t a way to obtain the stored value of an entity kv through VScript.

Adding this would be really useful, as it would not only allow you to add arbitrary kvs to entities for later reference in the script, but would also allow to you obtain a specific value which currently can’t be obtained (e.g. a set mass of a prop_physics).

I imagine the syntax to be smth like this:
<entityhandle>.GetEntityKeyvalue(keyvalue)

In cases where the given kv doesn’t exist, it should simply return null.

If you need me to expand on this idea anymore then let me know! :D
