[llvm] [Support] Fix copy-paste errors in YAMLTraits.h (PR #157022)

[Kazu Hirata via llvm-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/157022

has_MappingEnumInputTraits and its EmptyContext specialization define
Signature_validate to check for a member function named enumInput.
Note that in other YAML traits, Signature_foo is used to test the
presence of member method foo.

This patch fixes these copy-paste errors.
