Add a test that locklessly changes and exercises page protection bits
from various threads. This helps catch race conditions in the VMA

Hi Peter,
From the failures I see on the gitlab merge job, I think I need to resubmit with this new
test adjusted to loop less,
+ for (i = 0; i < 50000; i++) {
here.
The failing jobs are --enable-debug, and take about 115 seconds to run manually on our
aarch64 test host, exceeding the 90 second timeout.
I'll cut this down to 10000 loops and double-check times before resubmitting.
