[llvm] [memprof] Drop the trait parameter (NFC) (PR #89461)

[Kazu Hirata via llvm-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/89461

OnDiskIterableChainedHashTable::Create can default-contruct a trait
object for us.  We don't need to construct one on our own unless we
need to customize something (like a version number).
