Add custom 'Selected.*' type to PSCustomObject in Select-Object only once (#11548)

Before the fix Select-Object without parameters added custom 'Selected.' type to PSCustomObject even if this type was already present in TypeNames that was a memory leak in the edge case.
The cause of the problem was that Select-Object without parameters did not create a new object but forwarded the original.
The fix is to add custom 'Selected.' type only if object is original and it has not already custom 'Selected.*' type.
