Set Kokkos_ENABLE_Cuda_Relocatable_Device_Code=OFF by default for ATD…

…M builds (#2464, #2580)

Neither SPARC's nor EMPIRE's builds of Trilinos enable RDC for various reasons
(see #2464 and #2580).  This option is currently OFF by default but I am
setting this explicitly to OFF by default to make this clear.

We can set up a seprate build that eanbles this (see #2598)

This option is already off by default in Trilinos but this just makes it more
explicit that the current ATMD configutation of Trilinos does not enable this.
