RHI: Refactor Fence module to pure timeline semantics

Browse Source 
- Remove IsSignaled() from RHIFence interface (semantic inconsistency)
- Remove Reset() from OpenGL implementation (no D3D12 counterpart)
- OpenGL Fence now uses single GLsync + CPU counters for timeline simulation
- OpenGL Fence Initialize() now accepts uint64_t initialValue (was bool)
- Add comprehensive timeline semantics tests for all backends:
  - Signal increment/decrement scenarios
  - Multiple signals
  - Wait smaller than completed value
  - GetCompletedValue stages verification
- Update documentation to reflect actual implementation
