Subject: CPack: Add CPACK_NSIS_INSTALL_ROOT variable (#9148)

Control the root directory of the default directory presented to
the end user of an NSIS installer by a CPack variable.

Previously, the value used in the NSIS script was $PROGRAMFILES,
which is equivalent to the "ProgramFiles" environment variable.
That default value is still the same, but now a project may
override the value by setting this new variable.
