[clang-tools-extra] [clang-tidy] Add check 'bugprone-invalid-enum-default-initialization' (PR #136823)

The check can now warn for (default) initializations that are recursively inside a type structure (members of structs, elements of arrays). In these cases it can look difficult to find the member or place where the value with enum type exists. The check now only makes a single warning for the initialization but does not add notes to find the place of the enum value.
