Starting with VS 18 / cl 14.51, MSVC's constant evaluator
rejects a pointer-to-member in a constant initializer that also
contains any computed data, a consteval call or even a copy of a
constexpr object (C2127).
Hook records are now aggregate-initialized from literals only: the
computed name bytes (vtable symbol + display name) are baked into
char... template arguments and sizes/kinds are spelled inline.
