  • implement an internal bit sized int type
  • introduce __always_false trait
  • use the __uint_t in byteswap and fix unchecked ptx ISA and device's SM version
  • remove unused cuda/std/__type_traits/make_32_64_or_128_bit.h module

I love to see always_fase and the refactoring of byteswap.
A minor concern is that the PR mixes different topics.

also, please note that __builtin_bswap32 and friend are available in GCC < 10 but they are not detected by _CCCL_BUILTIN_BSWAP32

GCC <10 does not support __has_builtin which is one of the reason that in builtin.h a ton of builtins is explicitly enabled for GCC
