ntdll: Keep pagemap file open after first use of NtQueryVirtualMemory(MemoryWorkingSetExInformation).

1 syscall instead of 2 syscalls. Faster and simpler code.

Legends game periodically (every 30 seconds) calls this function
with up to 22k virtual addresses. All but 1 of them is valid. Due to
amount of queries addresses, and cost of seek+read, this causes this
function to take up to about 50ms. So framerate drops from ~150 FPS to
20FPS for about a second.

As far as I can see, returning 0 entries from this function, still makes
Apex Legend work.

But keep code correct, and optimise it by only performing pagemap read
when the address is valid.

This change get_working_set_ex reduces peek wall clock runtime from 57ms
to 0.29ms.

Tested on Linux, but similar change done for the BSD part.

Some drivers (AMD Radeon RX 6700 XT, with radeonsi from Mesa 22.2.0-rc3) emit
less than one invocation per pixel, presumably because they detect that the
shader control flow is uniform for all pixels. Having the control flow depend on
SV_Position avoids this test failure.

This fixes data race in ARM/ARM64 platforms, and prevents potential
memory access reordering by the compiler.
