Move accelerator API in arccore

[grospelliergilles]

The goal is to be able to use accelerator API using only Arccore. It will be useful for Alien for example.

The following this needs to be done:

• [ ] Move classes MDSpan in arccore_base (#2245 )
• [ ] Move class NumArray in arccore_collections
• [ ] Move classes about memory management (MemoryView, MemoryUtils, ...) in Arrcore
• [ ] Move classes needed by arcane/accelerator/core in Arccore. For example, there are classes about multithreading and profiling.
• [ ] Move classes in arcane/accelerator/core in Arccore
• [ ] Move some classes in arcane/accelerator in Arccore
