[clang-tidy] Don't use assignment for value-initialized enums
Summary:
The modernize-use-default-member-init check crashes when trying to
create an assignment value for a value-initialized enum because it isn't a
BuiltinType.
An enum cannot be initialized by assigning 0 to it unless a cast is added.
It could be initialized with an enumerator with the value 0, but there might not
be one.
Avoid these issues by ignoring the UseAssignment setting for value-initialized
enums.
Fixes PR35050.
