KEY_WOW64_32KEY support for registry keywords

[JFX]

Currently all Registry keyword support the 64 suffix to access native registry.
The counter part suffix 32 to access the WoW registry is missing.

Fixing this help file example could be nicely done,
without checking @AutoItX64 && appending Wow6432Node to the key.

For $i = 1 To 100
    Local $var = RegEnumVal("HKEY_LOCAL_MACHINE32\SOFTWARE\AutoIt v3\AutoIt", $i)
    If @error <> 0 Then ExitLoop
    MsgBox(4096, "Value Name  #" & $i & " under in AutoIt3 key", $var)
