ANDROID: zram: Add ioctl for per-process writeback operation 



Introduce a new ioctl command `ZRAM_ANDROID_IOC_PROCESS_WRITEBACK`.
Operate on a target process identified by a pidfd, and then iterates
through the virtual memory areas (VMAs) of the target process,
identifies pages that are swapped to the zram device, and then invokes
the corresponding writeback operation.
