[michaelrj-google]

Patch #73469 added a dependency from __support/bit.h to
__support/CPP/type_traits.h, but didn't add a dependency in the bazel.
This caused downstream build failures. This patch fixes the missing
dependency.

Thx for the fix @michaelrj-google! Unfortunately, layering-check upstream is weaker than the internal one so we can't easily detect these breakage. I usually try to also test the patch internally but it's more work and I didn't do it this time...
