Provide SetUserProfiles API to apply profiles at UID level.

This enables applying the freezer profile to an entire UID instead of
just individual process cgroups.

59af680023 Add support for optional cgroup attributes 
Cgroup attributes like io.weight or io.bfq.weight only exist if the
corresponding I/O scheduler has been loaded. Hence add support for
ignoring failures to write to a cgroup attribute that does not exist.

Bug: 213617178
Test: This patch has been tested in combination with patch "Migrate the blkio controller to the cgroup v2 hierarchy".
