SWDEV-335990 - Use GNUInstallDirs

GNUInstallDirs is used to allow the user to customize the install paths
of HIP, rather than using hardcoded locations.

See documentation for more information:
https://cmake.org/cmake/help/latest/module/GNUInstallDirs.html

Note that libdir must be overriden to "lib" before including
GNUInstallDirs, because by default, cmake tries to detect the libdir
path, but ROCm packaging would like to use lib by default for all
targets. This does not stop the user (or distros) from overriding.

Also note this change does no take into account the changes needed to
non-cmake files, such as perl scripts, so not all paths combinations are
necessarily functional.
