Merge bitcoin#24111: build: force CRCCheck in Windows installer

b3ccf26 build: force CRCCheck in Windows installer (fanquake)

Pull request description:

  Otherwise a user can pass `/NCRC` on the command line and bypass the
  CRC check, meaning they could use a corrupted installer. I can't think of
  a reason why we'd want to allow the use of corrupted installers.

  [NSIS docs](https://nsis.sourceforge.io/Docs/Chapter4.html#acrccheck):
  > Specifies whether or not the installer will perform a CRC on itself before allowing an install. Note that if the user uses /NCRC on the command line when executing the installer, and you didn't specify 'force', the CRC will not occur, and the user will be allowed to install a (potentially) corrupted installer.
