Add debugging capabilities to the CachingAllocator

[fwyzard]

PR description:

Extend the alpaka CachingAllocator to optionally fill with a configurable value all memory blocks that are: allocated, cached for re-use, re-used, or deallocated.

Extend the AlpakaService to configure the host and device CachingAllocators.

Add a simple test to load the AlpakaService.

---

To fill the NVIDIA GPU memory before every allocation or reuse with 0xA5, you can now use

process.AlpakaServiceCudaAsync.deviceAllocator.fillAllocations = True

To fill the NVIDIA GPU memory before every deallocation or caching with 0x5A, you can now use

process.AlpakaServiceCudaAsync.deviceAllocator.fillDeallocations = True

To use different values and combination for allocations, deallocation, caching, and reuse, the full options are

process.AlpakaServiceCudaAsync.deviceAllocator.fillAllocations = True,
process.AlpakaServiceCudaAsync.deviceAllocator.fillAllocationValue = 0xA5,
process.AlpakaServiceCudaAsync.deviceAllocator.fillReallocations = True,
process.AlpakaServiceCudaAsync.deviceAllocator.fillReallocationValue = 0x69,
process.AlpakaServiceCudaAsync.deviceAllocator.fillDeallocations = True,
process.AlpakaServiceCudaAsync.deviceAllocator.fillDeallocationValue = 0x5A,
process.AlpakaServiceCudaAsync.deviceAllocator.fillCaches = True,
process.AlpakaServiceCudaAsync.deviceAllocator.fillCacheValue = 0x96

To do the same for the pinned host memory used in the GPU transfers, process.AlpakaServiceCudaAsync.hostAllocator accepts the same options.

To do the same for AMD GPUs, replace AlpakaServiceCudaAsync with AlpakaServiceROCmAsync.

To do the same for the CPU memory used by the alpaka modules running on the host, replace AlpakaServiceCudaAsync with AlpakaServiceSerialSync.

PR validation:
