[PATCH] D146760: [clang-format] Treat NTTP default values as expressions

[Emilia Dreamer via Phabricator via cfe-commits]

rymiel added a project: clang-format.

clang-format already has logic to threat the right-hand side of an
equals sign. This patch applies that logic to template defaults,
which are likely to be non-template type parameters in which case the
default value should be annotated as an expression.
This should mostly only ever apply to bool and &&.

Fixes https://github.com/llvm/llvm-project/issues/61664
