Add the ability for a variable defined in a let in one $lookup stage to be referenced within a subpipeline of a nested $lookup, when all collections involved are sharded.
This should include serializing a constant-variable ExpressionFieldPath to be the constant, and to serialize a nested pipeline via serialize() rather than returning the unparsed version.
