Validate that all passed values are array data structures. Abort catalog
compilation if any value fails this check.
The following values will pass:
$my_array = [ 'one', 'two' ]
validate_array($my_array)
The following values will fail, causing compilation to abort:
validate_array(true)
validate_array('some_string')
$undefined = undef
validate_array($undefined)
