[Libomptarget] Revert changes to AMDGPU plugin destructors
These patches exposed a lot of problems in the AMD toolchain. Rather
than keep it broken we should revert it to its old semi-functional
state. This will prevent us from using device destructors but should
remove some new bugs. In the future this interface should be changed
once these problems are addressed more correctly.
This reverts commit ed0f21811544320f829124efbb6a38ee12eb9155.
This reverts commit 2b7203a35972e98b8521f92d2791043dc539ae88.

[Libomptarget] Deinitialize AMDGPU global state more intentionally
A previous patch made the destruction of the HSA plugin more
deterministic. However, there were still other global values that are not
handled this way. When attempting to call a destructor kernel, the
device would have already been uninitialized and we could not find the
appropriate kernel to call. This is because they were stored in global
containers that had their destructors called already. Merges this global
state into the rest of the info state by putting those global values
inside of the global pointer already allocated and deallocated by the
constructor and destructor. This should allow the AMDGPU plugin to
correctly identify the destructors if we were to run them.

[openmp][amdgpu] Tear down amdgpu plugin accurately
Moves DeviceInfo global to heap to accurately control lifetime.
Moves calls from libomptarget to deinit_plugin later, plugins need to stay
alive until very shortly before libomptarget is destructed.
Leaving the deinit_plugin calls where initially inserted hits use after
free from the dynamic_module.c offloading test (verified with valgrind
that the new location is sound with respect to this)

[Libomptarget] Add checks for AMDGPU TargetID using new image info
This patch extends the is_valid_binary routine to also check if the
binary's target ID matches the one parsed from the system's runtime
environment.
This should allow us to only use the binary whose compute capability
matches, allowing us to support basic multi-architecture binaries for
AMDGPU.
It also handles compatibility testing of target IDs of the image and
the enviornment.

[Libomptarget][NFC] Make Libomptarget use the LLVM naming convention
Libomptarget grew out of a project that was originally not in LLVM. As
we develop libomptarget this has led to an increasingly large clash
between the naming conventions used. This patch fixes most of the
variable names that did not confrom to the LLVM standard, that is
`VariableName` for variables and `functionName` for functions.
This patch was primarily done using my editor's linting messages, if
there are any issues I missed arising from the automation let me know.

[Libomptarget] Add basic support for dynamic shared memory on AMDGPU
This patchs adds the arguments necessary to allocate the size of the
dynamic shared memory via the `LIBOMPTARGET_SHARED_MEMORY_SIZE`
environment variable. This patch only allocates the memory, AMDGPU has a
limitation that shared memory can only be accessed from the kernel
directly. So this will currently only work with optimizations to inline
the accessor function.

[openmp][amdgpu] Replace unsigned long with uint64_t
Some types need to be 64 bit. Unsigned long is a hazard there.

[OpenMP] Increase opportunity for parallel kernel launch in AMDGPUs: add multiple hsa queue's per device in plugin
This patch extends the AMDGPU plugin for OpenMP target offloading from using a single HSA queue to multiple queues (four in this patch) per device. This enables concurrent threads to concurrently submit kernel launches to the same GPU.

[OpenMP] Part 2 of At present, amdgpu plugin merges both asynchronous
and synchronous kernel launch implementations into a single
synchronous version. This patch prepares the plugin for asynchronous
implementation by:
Privatizing actual kernel launch code (valid in both cases) into
an anonymous namespace base function (submitted at D115267)
- Separating the control flow path of asynchronous and synchronous
kernel launch functions** (this diff)

[OpenMP][AMDGPU] Switch host-device memory copy to asynchronous version
Prepare amdgpu plugin for asynchronous implementation. This patch switches to using HSA API for asynchronous memory copy.
Moving away from hsa_memory_copy means that plugin is responsible for locking/unlocking host memory pointers.
