Yunus Shaikh 815b8add6f test(agc): check that a settle read ends the driver's marking of an import ...

A Windows import under 1 MiB returns to the write watch once its settle
read has completed, though main-queue work submitted before the read may
have used the import first, and an earlier import of the same pages may
not have run its first use yet. On the NVIDIA driver (617.42) neither
marks the pages once the read has completed, so the rewatch needs no wait
for the main queue. The docs said the marking lasts until the import's
first GPU use completes; they now say that a completed GPU use ends it,
the settle read included.

agc_import_settle_first_use submits 4096 copies of a 64 KiB import on
the main queue before its settle read is queued. The import must return
to the write watch while the copies still run, and the driver must mark
none of its pages afterwards.

agc_import_settle_earlier_import records 4096 copies of a 64 KiB window
import, replaces it with the import of its whole 128 KiB range, and
submits the copies only once the range is back in the write watch. The
driver must mark none of the range's pages while they run. A driver that
keeps marking fails either test.
