HIPAllocatorMasqueradingAsCUDA and HIPCachingAllocatorMasqueradingAsCUDA are now proper complete wrappers of HIPAllocator and HIPCachingAllocator, respectively. HIPAllocatorMasqueradingAsCUDA now subclasses HIPAllocator instead of Allocator. This fixes usability of hipify replacing c10::cuda::CUDACachingAllocator::get() where callers expect a CUDAAllocator to be returned but instead were getting a very thin Allocator shim instead. This also fixes using cudagraph trees with torch compile. The hip:0 device was not being replaced by the cuda:0 device in all methods.
