This reverts most of commitcf2a68d2ff, and bits ofcbea5a1149. First of all, with ARM borrowing x86's implementation, the logic to set the pool size should have been common, not duplicated. Introduce libxl__domain_set_paging_mempool_size() as a shared implementation, and use it from the ARM and x86 paths. It is left as an exercise to the reader to judge how libxl/xl can reasonably function without the ability to query the pool size... Remove ARM's p2m_domctl() infrastructure now the functioanlity has been replaced with a working and unit tested interface. This is part of XSA-409 / CVE-2022-33747.
