VS: Do not regenerate build system concurrently with CMP0147

Browse Source 
The VS generators add a custom command to `CMakeLists.txt` to re-run
CMake when input files have changed.  Mark this custom command as if it
were specified with `USES_TERMINAL`.  We already do this for the
equivalent `rebuild_cache` target in Makefile and Ninja generators.

This matters since commit d6353e74b4 (VS: Add policy to build custom
commands concurrently, 2023-03-10) because with policy CMP0147 set to
NEW, we now add `BuildInParallel` in `.vcxproj` file entries for custom
commands that do not have `USES_TERMINAL` set, but we do not want to
re-run CMake concurrently with other custom commands.
