Pull request overview
This PR adds a GetFullPath() method to the AbsolutePath struct to provide an API that fully replicates Path.GetFullPath behavior, including resolving relative path segments ("." and "..") and normalizing directory separators on Windows. This enables replacing direct Path.GetFullPath calls in task code with a more controlled API.
Changes:
- Added
GetFullPath()method with optimization to avoid allocations when no normalization is needed - Added comprehensive unit tests for both Windows and Unix platforms

Context
It is quite often that
Path.GetFullPathis used in the tasks code. For enlightening we would want to replace it with our own API. The candidate wasTaskEnvironment.GetAbsolutePathfor replacing.However, they do not do the same set of actions.
TaskEnvironment.GetAbsolutePathonly absolutizes the path but does not resolve possible "." and ".." in the path or normalize path separators on Windows.For some scenarios this is critical, for some that does not matter. We should provide an option for fully copy
