Const enum initializers reject qualified enum member references #3630

const enum First { A = 4 }
const enum Second { B = First.A }
console.log(Second.B);

TypeScript 6.0.3 accepts this with --ignoreConfig --strict --target ES2022. Its emitted JavaScript prints 4. SharpTS at 72455db66 rejects it with --no-tsconfig --strict --noEmit and reports Expression type 'Get' is not allowed in const enum initializer.

A member of another const enum should be available as a compile-time enum initializer value. Found while verifying #3620, which covers const variable references. #3605 covers the regular enum case.
