* Add experimental reattachment support for ROCprofiler-SDK

This commit introduces experimental reattachment functionality allowing tools
to dynamically reattach to running processes with comprehensive design changes
to support multiple attach/detach cycles:

**Core Reattachment API:**
- Add rocprofiler_tool_configure_result_experimental_t with tool_reattach/tool_detach callbacks
- Add rocprofiler_call_client_reattach and rocprofiler_call_client_detach C exports
- Implement reattachment tracking in rocprofiler_register_attach to differentiate
initial attachment from reattachment cycles
- Add rocprofiler_register_invoke_reattach for handling reattachment requests

**Design Changes - Registration System Flow:**
The registration system now supports a dual-path initialization:

1. Initial Attachment Flow:
    - rocprofiler_register_attach() -> rocprofiler_register_invoke_all_registrations()
    - Full tool initialization with complete context setup
    - Sets prev_attached atomic flag to track state

2. Reattachment Flow:
    - rocprofiler_register_attach() detects prev_attached=true -> rocprofiler_register_invoke_reattach()
    - Bypasses full re-initialization, calls client reattach callbacks instead
    - Preserves existing contexts and buffers, only reactivates profiling services

**Design Changes - Tool Library Loading:**
Enhanced rocprofiler-register library loading with function pointer resolution:
- Extended rocp_set_api_table_data_t tuple to include reattach/detach function pointers
- Automatic symbol resolution for rocprofiler_call_client_reattach/detach functions
- Support for both LD_PRELOAD and dlopen scenarios with consistent callback availability

**Design Changes - Context Management:**
Introduced dual context systems for attachment scenarios:
- get_contexts() - Original contexts for standard tool initialization
- get_attach_contexts() - Separate context map for attachment-specific lifecycle
- attach_init() - Creates contexts for ALL buffer tracing services using existing buffers
- attach_start() - Selectively starts contexts based on configuration options
- attach_detach() - Cleanly stops and destroys attachment contexts

**Design Changes - Buffer Management:**
Added reset_tmp_file_buffer() template for clean reattachment state:
- Properly closes and removes old temporary files
- Deletes existing file_buffer instances to prevent stale file position tracking
- Creates fresh file_buffer instances for clean reattachment cycles
- Addresses core issue where file position metadata becomes stale between cycles

**Design Changes - Environment Variable Injection:**
Added ROCP_REGISTERED_TOOL_ATTACH environment variable:
- Distinguishes attachment-loaded tools from LD_PRELOAD scenarios
- Enables registration system to apply attachment-specific logic
- Helps tools adapt behavior for attachment vs standard initialization

**Attachment Context Management:**
- Add attach_init/attach_start/attach_detach functions for dynamic context lifecycle
- Add reset_tmp_file_buffer template for clean reattachment state management
- Implement get_attach_contexts() for tracking active attachment contexts

**Test Infrastructure:**
- Add projects/rocprofiler-sdk/tests/rocprofv3/reattach/ comprehensive test suite
- Include reattachment test scripts with unified attachment/detachment cycles
- Add validate.py with trace data validation for kernel, memory copy, HSA API, and agent info
- Add conftest.py for JSON and CSV data loading utilities

**Configuration Updates:**
- Update CMakeLists.txt to include reattachment tests in build system
- Add environment variable ROCP_REGISTERED_TOOL_ATTACH for attachment state tracking
- Enhance rocprofiler-register library loading with reattach/detach function resolution

**Flow Impact Analysis:**
This design enables robust multi-cycle attachment by:
1. Preventing duplicate initialization on reattachment
2. Maintaining separate context lifecycles for attachment vs standard operation
3. Ensuring clean temporary file state between attachment cycles
4. Providing tools with explicit reattach/detach callback hooks
5. Supporting both programmatic and environment-based tool configuration

The experimental nature allows for iteration on the API while establishing
the foundation for production-ready dynamic profiling capabilities.
