file: Add GENERATE command to produce files at generate time The idea is to write to a temp file which contains generator expressions, and at generate time, evaluate the generator expressions, and write the result to a file. Because executables on Windows are limited in the length of command line it is possible to use, it is common to write command line arguments to a file instead and specify the file as a source of arguments. This new FILE(GENERATE) subcommand allows the use of generator expressions to create such files so that they can be used with add_custom_command for example.

Tests: Activate tests accidentally excluded from Xcode The generator name is "Xcode", not "XCode". Fix this typo. Explicitly exclude the SubDirSpaces test on Xcode because it does not work. Also tell the RunCMake.File_Generate test when Xcode is not multi-config so it can exlcude the OutputConflict case. Inspired-by: Daniele E. Domenichelli <daniele.domenichelli@iit.it>
