Jason A. Donenfeld 642a56e165 memmod: import from wireguard-windows
We'll eventually be getting rid of it here, but keep it sync'd up for
now.

Jason A. Donenfeld 3957e9b9dd memmod: register exception handler tables
Otherwise recent WDK binaries fail on ARM64, where an exception handler
is used for trapping an illegal instruction when ARMv8.1 atomics are
being tested for functionality.

Jason A. Donenfeld bad6caeb82 memmod: fix protected delayed load the right way
The reason this was failing before is that dloadsup.h's
DloadObtainSection was doing a linear search of sections to find which
header corresponds with the IMAGE_DELAYLOAD_DESCRIPTOR section, and we
were stupidly overwriting the VirtualSize field, so the linear search
wound up matching the .text section, which then it found to not be
marked writable and failed with FAST_FAIL_DLOAD_PROTECTION_FAILURE.

Jason A. Donenfeld c89f5ca665 memmod: disable protected delayed load for now
Probably a bad idea, but we don't currently support it, and those huge
windows.NewCallback trampolines make juicer targets anyway.

Jason A. Donenfeld 497ba95de7 memmod: do not use IsBadReadPtr
It should be enough to check for the trailing zero name.

Jason A. Donenfeld 3d83df9bf3 memmod: apply explicit build tags to _32 and _64 files
Since _32 and _64 aren't valid goarchs, they don't match _GOOS_GOARCH,
and so the existing tags wind up not being restricted to windows-only.
This fixes the problem by adding windows to the tags explicitly. We
could also fix it by calling the files _32_windows or _64_windows, but
that changes the convention with the other single-arch files.
