Add TCGC exact-name support to TypeScript emitter

[Qiaoqiao Zhang (qiaozha)]

Summary

• honor TCGC exact() names across TypeScript clients, operations, parameters, models, properties, and enum members
• keep exact names consistent in serializers, classic clients, generated samples/tests, and client hierarchy paths
• report deduplicated warnings at emission sites when an exact name cannot form a valid TypeScript identifier
• add focused unit coverage and opt the emitter into the shared exact-name Spector scenario with a generated API baseline

Validation

• mise exec -- pnpm format
• mise exec -- pnpm lint
• mise exec -- pnpm --filter @azure-tools/typespec-ts build
• mise exec -- pnpm --dir packages/typespec-ts unit-test (669 tests)
• mise exec -- pnpm --dir packages/typespec-ts test-next (254 tests)
• exact-name Spector integration (5 tests)
