[cfe] Change MapPattern.key to Expression
The key can only be an Expression but was unneedingly wrapped in a ConstantPattern. Since the shared type analysis only handles map pattern keys as expressions, the expected properties of ConstantPattern were not set. Amongst these were the static type of the key expression, which is know passed directly to the handleMapPatternEntry method.
