LibJS: Add vector of local variables in ExecutionContext

Browse source 
Now ExecutionContext has vector of values that will represent values
of local variables.

This vector is initialized in ECMAScriptFunctionObject::internal_call()
or ECMAScriptFunctionObject::internal_const() using number of local
variables provided to ECMAScriptFunctionObject by the parser.
