Expose 'samDesired' param to all Advapi32Util#registry* methods

Added overloads to `c.s.j.platform.win32.Advapi32Util` methods which
allow the caller to specify `samDesiredExtra` to request additional registry
key security and access rights

It also allows accessing alternative registry views by specifying:
KEY_WOW64_64KEY or KEY_WOW64_32KEY

Closes: #379
