Ryan Houdek a42b659af9 ELFCodeLoader: Fixes Proton Experimental on 48-bit VA systems ...

This is a tricky situation that wine-preloader allocates the lower
32MB of stack space through fixed address mmap with MAP_FIXED.

They can't use mmap with an address hint nor MAP_FIXED_NOREPLACE because
it changes behaviour. mmap won't give you the allocation inside the
stack space even if you check `/proc/self/maps` that space isn't yet
allocated. The growable space of the stack blocks those allocations.

So the wine peeps might be SOL if they actually require this allocation
to exist.

To replicate this, allocate the application stack at the same location using an address hint.
This will give us the correct region on a 48-bit VA system, while also
letting it select a different region on a 36-bit VA system.
