Re-enable file descriptor caching and add option to skip caching

This reverts commit bee9f571
"libprocessgroup: Disable file descriptor caching temporarily" and adds
option to use SetTaskProfiles and SetProcessProfiles without file caching.
This option is used from JNI to avoid access denials because cached files
are not whitelisted for JNI usage.
