DMN14 — New built-in function to create a new context

Currently, it is not possible to create or modify a context dynamically. A context can only be declared statically.

We need to model a decision that gets a context, adds or removes entries, and returns a new context. For example, by using the get entries() function of a given context and modifying the entry list with a filter expression or list functions.

Suggestions:

• introduce a new conversion built-in function for context as reverse function to get entries()
• it is named `context`
• it has one argument: entries... (type: list<context<Any>>) - each context must have two entries with the keys: "key" and "value"
• it returns a new context that includes all given entries

context([{"key":"a", "value":1}, {"key":"b", "value":2}])
// returns: {a:1, b:2}
