ENH: improve consistency in handling of global IOobjects (#3045)

- replace typeGlobal() global function with is_globalIOobject
  traits for more consistent and easier overriding.

- relocate typeFilePath() global function as a member of IOobject
  for consistency with typeHeaderOk.

BUG: faSchemes, fvSchemes not marked as global file types

- caused issues with collated
