Map the spack skylake arch to Kokkos BDW, rather than SKX (#16583)

Browse Source 
SKX includes AVX-512 extensions that consumer Skylake processors do
not have. Therefore, map Skylake to the prior arch to work on
these systems. Skylake-X processors will still map as the
skylake_avx512 spack arch and get the correct optimzations.

# @AndrewGaspar: Kokkos does not have an arch for plain-skylake - only
# for Skylake-X (i.e. Xeon). For now, I'm mapping this to Broadwell
# until Kokkos learns to optimize for SkyLake without the AVX-512
# extensions. SkyLake with AVX-512 will still be optimized using the
# separate `skylake_avx512` arch.
