Support dynamically defined ChoiceLabelProperty

[jdhitsolutions]

When using Read-SpectreSelection or Read-SpectreMultiSelection, the ChoiceLabelProperty must be unique.

It would be very helpful to dynamically define the label property with a script block.

Read-SpectreMultiSelection -AllowEmpty -Choices (ps pwsh) -ChoiceLabelProperty {"$($_.name) [$($_.id) - $($_.StartTime)]"}

The user could try something like this:

$p = ps pwsh | select *,@{N="Proc";E={ "$($_.name) $($_.id) - $($_.StartTime)" }},
Read-SpectreMultiSelection -AllowEmpty -Choices $p -ChoiceLabelProperty proc

But this feels more cumbersome, and technically this writes a selected object and not the original native objec.
