QEMU 6.0.0 - Improve NSIS installer script

@stweil

Could be possible to improve NSIS installer script

• To show on main instalelr window on top left program version and platform (32bit or 64bit)
  

• To setup in File Properties Appname/File Version/Product Name/Version/Copyright
  

• To setup correctly in Windows Program Add/Remove list the right icon and product name as Product name + plaform (ex. QEMU (64bit)"?
  

Thanks.

Thanks for these suggestions. At least some of them should be possible. I'll have to check for the rest.

I already tested and you can do all of these.
If you have the installaer script (.iss fiel) I can explain better.

@bovirus, here is a test version of the installer which tries to fix this issue.
