1) Since g_devices is not initialized when stream_per_thread constructor
is called on windows, m_streams is empty when hipDeviceReset is called.
2) clear_spt tries to access empty vector causing segfaults in
hipDeviceReset call.
3) on linux ROCCLR_INIT_PRIORITY makes sure that g_devices is initialized
first before tls constructor creates stream_per_thread object.

This change adds a new HIP API `hipExtHostAlloc` which preserves
the functionality of `hipHostMalloc`.

SPT is destroyed with hipDeviceReset(). If a
stream is created right after reset, the same
object id could be reused. Later SPT destructor
incorrectly verifies that the stream is valid
referring to the reused object id causing the
corruption.

This change adds fixes in optimized multistream path for childGraph uses cases.
1) For childgraph nodes, rely on runNodes() only to process
the childgraph and skip calls to createCommand and enqueueCommands.
This ensures that the start/end markers are enqueued correctly
with respect to the childGraph commands.
In addition, the runNodes() for the childgraph should be called after
the dependency walkthrough to make sure that the subgraph is executed once.
2) Nodes with no outgoing edges should be marked
as a leafs regardless of which stream they are assigned to.
This is to ensure that marker dependencies from nodes
that run on non-zero stream to subgraph leafs that run on zero stream
are still set up correctly.

When source or destination pitch is set to zero in hip_Memcpy2D struct
it should default to WidthInBytes + [src/dst]XInBytes

Releasing graph exec after wait completes and before delete hip::stream obj
during stream destroy.

- Added the optimized multi stream path in graph execution. It uses a fixed number of async streams in the execution
- Optimize the launch latency, where commands
creation and execution is done at the same time
- Optimize the scheduling to use less barriers and waiting signals if
the same queue can be detected
- The new path is controlled by DEBUG_HIP_FORCE_GRAPH_QUEUES
environment variable, where 0 will use the original path and any other
value will force the number of asynchronous queues for execution
- DEBUG_HIP_FORCE_ASYNC_QUEUE can force single queue async
execution in graphs(applicable for Navi families only)

=> Added support to capture multiple AQL Packets.
=> Added Interface to callback to hip runtime from rocclr to allocate
kernel args from the graph kernel arg pool.
=> Enabled Support to capture memset node.

hipDeviceSynchronize called from __hipUnregisterFatBinary
accesses static maps and monitors. This change ensures these ojects
are not destroyed before __hipUnregisterFatBinary is called.
Additionally it disables the teardown process for static build.

This issue was happening because of incorrect usage of getStream call,
if we get the null stream first and then typecast it, and call on
getStream again, we lose the advantage of simply passing "nullptr" to
indicate NULL stream. Thus we enter the waitActiveStream call and add
barriers to sync across streams.

Also in the scope of SWDEV-467540.
Fix sporadic crash in Unit_hipStreamAddCallback_MultipleThreads by
deferring release() of block_command.
The test will invoke 1000 threads on the same stream thus there
is a chance to free block_command too early in original code.
By deferring release() of block_command we can make sure block_command
is always valid during calling block_command->notifyCmdQueue().

Capture AQL packets during GraphInstantiation and enqueue AQL packets during graph launch.
Added support to capture single graph memset node.
Capture support for memset node is currently disabled.
Memset capture will be enabled when capture for multiple packets are supported..

On some platforms user can ask for extended shared memory for a
particular kernel in some cases. This feature does not exist on HIP at
the moment. So we are setting it to sharedMemPerBlock which is the
maximum user can expect for their kernels.

For refactoring of childGraph to have its own graphExec,
kernelArgs needs to be separated from the graphExec object.
All the childNodes part of graph should share same kernelArg pool.
Otherwise we endup creating multiple device kernel arg memory chucks
for single graphExec.

This change modifies the readback mechanism to use a pointer to volatile
instead of a volatile pointer. This ensures that the compiler does not
optimize away the read operation.

- Introduce a lock when checking isUserObjectValid. We need a lock
here as one can remove the userObject T2, leading to buffer overflow
when checking ranges in T1.

If graph has multiple branches, End command is enqueued on launch stream which
makes sure all the internal parallel streams are finsihed.
When node is removed from the graph, indegree and outdegree are not getting update correctly for parent, child nodes and
resulting in endNode not having deps on parallel commands. Resulting in graph sync issues.
