New ScopedTimer and small cmake fixes

[ChronoInferna]

This pull request improves the timer utilities and build configuration for the project. The main changes include refactoring the Timer and ScopedTimer classes for better usability and safety, updating their implementation, and enhancing the CMake presets to support multiple build types and compilers. Additionally, tests for ScopedTimer are now enabled.

Timer utility improvements:

• Refactored the Timer and ScopedTimer classes in timer.hpp and timer.cpp to consistently use an internal clock type alias, improved the interface of ScopedTimer to output elapsed time via a reference, and implemented its destructor for automatic timing. [1] [2]
• Enabled and implemented a test for ScopedTimer in test_timer.cpp, ensuring it correctly measures elapsed time.

Build configuration enhancements:

• Updated CMakePresets.json to define separate build directories for each preset (e.g., build-debug, build-release, build-clang-debug, etc.), and added a new msvc-debug preset for MSVC builds. This makes it easier to manage and switch between different build configurations. [1] [2] [3]
