Add input() and add_output() methods to GraphBuilder

[justinchuby]

This pull request adds new methods to the GraphBuilder class to simplify the creation and management of graph inputs and outputs, and introduces corresponding unit tests to ensure their correct behavior. The changes improve the usability and reliability of the graph-building API.

Enhancements to the GraphBuilder API:

• Added a new input method to GraphBuilder for creating and registering graph input values with support for specifying name, dtype, shape, type, constant value, and metadata properties.
• Added a new add_output method to GraphBuilder to append an output value to the graph and optionally rename it.
