Improve flags handling

- Replace i16 with PollEvents bitflags for better readability and safety
- Update poll logic to use new PollEvents enum
- Improve code structure and remove redundant constants

Refactor unwinding related code

- Add weak panic handler function for platform-agnostic panic handling
- Enable the `linkage` feature to support weak function linkage

- Implement is_empty method for StackTrace struct
- Provides a clear way to check if the stack trace is empty

- Add len method to return the number of captured stack frames
- Implement Deref trait to allow accessing stack frames directly
- Update stack_frames method to use Deref

- Updated function name to better reflect its purpose and improve code readability

- Remove IDisplayableStackTrace trait and its implementation for StackTrace
- Use StackTraceWalker to handle stack frame enumeration and printing

This refactor extracts the platform-specific unwinding logic from `StackTrace<N>::begin_unwind`
into a new `StackTraceWalker` structure that accepts a callback to receive frames. This allows
greater flexibility and reuse, and paves the way for future extensions like dynamic trace
collection, filtering, or early termination.

- Introduce `BacktraceCallbackDelegate` trait alias for frame callbacks
- Create `StackTraceWalker::begin_unwind` for general-purpose unwinding
- Refactor architecture-specific logic to invoke a callback instead of building traces
- Preserve existing `StackTrace<N>` API and semantics with no functional changes

No behavior change is introduced. API remains backward-compatible.

this is a workaround

This directory is no longer used. Use `SetupXXWorkspace.sh`es in the root directory
