Unity runner and parser for unit testing feature

[brianignacio5]

Description

Remove dependency to pytest, read serial output directly to parse unit test results.

This pull request introduces a new infrastructure for running ESP-IDF unit tests using the Unity test framework over a serial connection. The main changes include implementing a serial port capture utility, a Unity test output parser, and a test runner that orchestrates the process. The existing unit test adapter is refactored to use these new components, enabling more robust and accurate test execution and reporting directly from the device.

Serial communication and Unity test orchestration:

• Added UnitySerialCapture class to handle serial communication with ESP32 devices, including connecting, capturing output, performing hardware resets, and sending commands to the device.
• Implemented UnityTestRunner class to manage the test execution flow, interact with the serial capture, and parse test results from device output.

Unity test result parsing and types:

• Added UnityParser class for parsing Unity test framework output into structured test result objects, supporting both individual and multiple test results.
• Defined TypeScript interfaces for Unity test results, suites, summaries, and serial port configuration in types.ts.

Integration with existing unit test adapter:

• Refactored adapter.ts to use the new Unity test runner, including serial port selection, baud rate configuration, and improved error handling for test execution. [1] [2]
• Updated imports and dependencies in adapter.ts to support new functionality. [1] [2]

Type of change

• New feature (non-breaking change which adds functionality)

Left a comment regarding the use of "console" for warnings and errors instead of using "Logger" and noticed some console.logs as well

Confirmed Working on Windows, Ubuntu and MacOS environment.
It is a quicker interface to run the unit tests.
