Darwin: prefix internal osx variables with "_" to hide them from users
A simple CMakeLists.txt on osx shows that variable "d" is set
(but empty) by the system modules. this pollutes the user's
variable namespace. I noticed this when I created a library
target "d" and got unexpected policy CMP0054 warnings when
trying to find_package(d CONFIG REQUIRED) (triggered from the
generated "d-targets.cmake" ...). Note that non-"_" prefixed
internal variables are ok within functions due to scoping rules.
Fixes: #20898
