* Introduce HsaKFDContext structure and infrastructure for multiple KFD contexts, enabling
independent contexts within a single process.
* Refactor core components (queue, event, FMM, topology) to be context-aware,
using explicit HsaKFDContext parameters instead of global state.
* Replace global hsakmt_kfd_fd with context-specific file descriptors, ensuring full context isolation.
* Maintain backward compatibility by redirecting legacy APIs to use the primary context.
This refactoring establishes a foundation for multi-context support while preserving existing functionality.

This builds on a prior change that allowed for allocating
a user-mode queue's packet buffer in device memory to also
allocate the queue struct in device memory. This provides
additional latency benefits particularly for cases where
dispatches are performed from the GPU itself. Flags are
added to support the various use cases.

Currently registering graphics memory without specifying a target
node will return a memory handle that's not a virtual address.
As a result, ROCr is forced to register with a target node for
IPC usage.
Mapping memory without specifying a target node afterwards will
result in mapping to the target node that was imported because the
previous import call flags this node targeting action to future mapping.
For ROCr IPC usage, ROCr wants to map to all GPU nodes if the target node
is not specified.
Allow the caller to register graphics handles that returns a virtual
address without having to specify the target node so that the caller
can make a subsequent map call to all GPUs.

To support fully-static library ROCm builds, ensure that all global
symbols are prefixed with something meaningful to avoid collisions with
other libraries
A script was made using" objdump -C -t" to get a list of symbols,
then checking if the global symbols have a meaningful prefix (for thunk:
hsakmt or kmt in various cases)

add CHECK_KFD_OPEN in all APIs to catch this application bug earlier
without calling to KFD.
