Fix separate compilation -dc (#433)

Browse Source 
* Fix separate compilation `-dc`

- when cutlass is included in multiple compilation units
  compiled with `-dc` OOB_NAN_F16x8 device constant is
  instantiated multiple times causing
  Multiple definition of '_ZN7cutlass4arch13OOB_NAN_F16x8E' error
  This PR makes this variable a local constant as it is not
  modified during runtime
