Added uint32_t DPCTLDevice_GetMaxClockFrequency(__dpctl_keep const DPCTLSyclDeviceRef DRef) and uint64_t DPCTLDevice_GetMaxMemAllocSize(__dpctl_keep const DPCTLSyclDeviceRef DRef).

These expose info::device::max_clock_frequency and info::device::max_mem_alloc_size descriptors.
Corresponding Python API are attributes dpctl.SyclDevice.max_clock_frequecne and dpctl.SyclDevice.max_mem_alloc_size.
