Implement vm_page_reclaim_contig_domain_ext() to reclaim multiple contiguous regions at once. This makes it more efficient for users that need multiple contiguous regions to reclaim those regions efficiently. This is needed because callers like ktls may need to reclaim many contiguous regions, and each scan of physical memory can take multiple seconds on a large memory machine (order of 100GB of RMA). Rather than modifying the core algorithm, I extended vm_page_reclaim_contig_domain() to take a "desired_runs" argument to allow the caller to request that it reclaim more than just a single run. There is no functional change intended for all existing callers. The first user for this interface is the ktls code (https://reviews.freebsd.org/D39421). By reclaiming multiple runs, ktls goes from consuming hours of CPU to refill its buffer zone to just seconds or minutes.
