Proper CMake tree

[edimarvalentin]

This pull request refactors the CMake build and test configuration to improve modularity and maintainability. The main change is moving test setup logic for dense_mread and sparse_mread into their own subdirectories, simplifying the root CMakeLists.txt and making test management more organized. Additionally, the GitHub Actions workflow is updated to run tests from the correct directory.

CMake configuration refactoring:

• Moved test configuration for dense_mread and sparse_mread out of the root CMakeLists.txt and into separate CMakeLists.txt files within their respective subdirectories, cleaning up the main build file and improving modularity. [1] [2] [3] [4]
• Added a new test/CMakeLists.txt to enable testing and include the dense_mread and sparse_mread subdirectories, centralizing test setup.

CI workflow update:

• Changed the working directory for the test step in .github/workflows/cmake-single-platform.yml to build/test, ensuring tests are executed from the correct location after the new test structure.
