Reland "Batch compacted pages to reduce number of uffd ioctls."
This reverts commit 208ade91673d0fc85041c024a158be0207d0bc3b.
Reason for revert: Resolving linear-alloc crashes
Fix the case where compaction phase is done in STW pause. This happens
when the kernel doesn't support MREMAP_DONTUNMAP but supports
userfaultfd, like in case of golem.
Also incorporates changes to copy/zeropage ioctls to absorb EAGAIN
thrown by kernel when mmap_lock is contended and repeat the ioctl for
remaining pages.
