FPP v2.0 integration

[tiffany1618]

Change Description

This PR integrates FPP v2.0, which adds support for C++ generation of unit test harness classes, with F Prime.

Unit tests for the FPP unit test autocoder have been added to the existing tests for FPP components.

Changes to Generated C++ Code for Unit Test Harnesses

General

• Prepend the component name to the generated file names, e.g. [ComponentName]TesterBase.cpp instead of TesterBase.cpp. This allows the generation of test harness classes for multiple components within the same directory.

TesterBase classes

• Reorganize class members (follows the same pattern as the reorganization of class members for component base classes, see FPP v1.3.0 integration #2103)
• Change typedef struct {...} [name]; to struct [name] {...};
• Move initialization of m_param_[paramName]_valid variable members from the init function to initializer lists in the constructor
• Fix issue where [portName]_static and dispatch function implementations for special ports are not generated when the corresponding special port constructs do not appear (e.g. a component contains command ports, but no commands)
• Change sizeof([serializableType]) to [serializableType]::SERIALIZED_SIZE where appropriate in the dispatchEvents function

To do before merging

• Merge unit test code generation into FPP
• Integrate unit test code generation with fprime tools
• Create FPP pre-release to test PR
• Create FPP release v2.0

The top-level comment sets out the procedure for integrating FPP 2.0 into F Prime. However, the changes in this PR just improve code coverage of existing tests. I think this PR can be reviewed and merged now. Perhaps we should move the top-level comments and checklist to another issue focused on FPP 2.0 integration.

CI passes except for one failure that seems unrelated to this PR.

Looks good!
