Fix to issues with PVTU writer 12/24

[elieberman3]

Description

Fixed issues with PVTU writer associated with running on GPUs. Also moved the t=0 viz output code to after many inits to ensure fields are defined.

Adapted GPU incompatible variables to local dual arrays for use within FOR_ALL.
Converted FOR_ALL's within writer to FOR_ALL_CLASS's to use non-local variables correctly.
