Without this, a late-connecting client receives the deferred
GpuNewContext but not the GpuContextName, so the GPU context appears
unnamed in the profiler.
Add check_gpu_ctx_name tool to verify context names in captured traces.

Two issues prevented the rocprofiler GPU backend from working with
TRACY_ON_DEMAND:
1. GpuNewContext not deferred: When a Tracy client connects late (on-demand
mode), it never receives the GPU context creation message because the
GpuNewContext queue item was not buffered via DeferItem. This caused an
assertion failure (ctx == nullptr) in the capture/profiler when
processing GPU zone events. Add the same DeferItem pattern used by the
CUDA backend.
2. Kernel symbols dropped before init: The data->init guard at the top of
tool_callback_tracing_callback() blocked kernel symbol registrations
(CODE_OBJECT_DEVICE_KERNEL_SYMBOL_REGISTER) which happen at HIP init
time, before any Tracy client connects. Move the init guard after the
code_object block so symbols are always recorded, while dispatch and
memory-copy events are still gated on initialization.

This provides some instructions and tips for the manual. Also:
* Made the calibration feature a CMake option
* Cleaned up some minor code issues
* Fixed an issue with the calibration
* Incremented patch number
Synchronizes the GPU timeline periodically. This is needed to counter
network time updates that cause drift in the GPU and CPU timeline.
