cgsl_0409: Data transfer for component deployment

ID: Title	cgsl_0409: Data transfer for component deployment
Description	To model data transfers:
	A	Use signals between callable functions.
	B	When branching or merging transfer signals, in the Embedded Coder dictionary, add $X to the Function Naming Rule fields. Compliance with this rule is enforced during code generation.
	C	Do not branch data transfer signals to the root-level output port. Compliance with this rule is enforced during code generation.
Notes	When merging data transfer signals, ensure that both signals are mutually exclusive.
Rationale	The generated code aligns with the data communication method required by the platform environment for concurrent execution.
Model Advisor Check	A Model Advisor check is not provided for this guideline.
