Fix #135217: ColorManage Settings RNA paths incomplete/wrong

`ColorManagedDisplaySettings`, `ColorManagedViewSettings`,
`ColorManagedInputColorspaceSettings` were affected since these are used
from multiple places (Scene, File output nodes, ..).

Similar to how we are getting the path for `ImageFormatSettings` (which
pretty much has the distinction logic already), we can do so for the
ColorManage Settings as well (piggbacking on the already correct path to
the `ImageFormatSettings`.

With this, we can also remove these "known failures" from the test
introduced in 4032b853c3.
