Support splatting `-ArgumentList` with hashtable too

[o-l-a-v]

Summary of the new feature / enhancement

Start-ThreadJob (and Start-Job for reference) currently only supports splatting -ArgumentList with array:

• https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_splatting?view=powershell-7.4#splatting-with-arrays

This means some example code must be like this:

$JobsUsingArray  = [array](
    1 .. 3 | ForEach-Object -Process {
        Start-ThreadJob -ScriptBlock {
            [OutputType([System.String])]
            Param(
                [Parameter(Mandatory,Position=0)][string]$SomeParameter
            )
            Write-Output -InputObject $SomeParameter
        } -ArgumentList ('Hello {0}' -f $_)
    }
)
Receive-Job -Job $JobsUsingArray -Wait

which returns:

Hello 1
Hello 2
Hello 3

I much prefer to splat using name of the input parameters, so splatting with hashtable. I'd like this to work too:

$JobsUsingHashtable = [array](
    1 .. 3 | ForEach-Object -Process {
        Start-ThreadJob -ScriptBlock {
            [OutputType([System.String])]
            Param(
                [Parameter(Mandatory)][string]$SomeParameter
            )
            Write-Output -InputObject $SomeParameter
        } -ArgumentList @{
            'SomeParameter' = [string] 'Hello {0}' -f $_
        }
    }
)
Receive-Job -Job $JobsUsingHashtable -Wait

which returns

System.Collections.Hashtable
System.Collections.Hashtable
System.Collections.Hashtable
