Accessing 32-bit registry view from 64-bit process

[Brainy0207]

Some keys in the registry are redirected for 32-bit and 64-bit processes.
Is there a way to access the 32-bit view of the registry from a 64-bit process (and vice versa) using the wil helpers?

Usually you would specify KEY_WOW64_32KEY or KEY_WOW64_64KEY when opening the key:

#555 Added access to the 64-bit registry.
32-bit access is still missing so I created my own PR.
