internal/optional.h: move macro from types/optional.h

ABSL_OPTIONAL_USE_INHERITING_CONSTRUCTORS is only used within this file.
additionally check the macro with #ifdef rather than #if, fixes -Wundef
warning:
'ABSL_OPTIONAL_USE_INHERITING_CONSTRUCTORS' is not defined, evaluates to 0

It evaluates the input at runtime and allocates stack space accordingly.

This removes a potential fallback into snprintf, improves performance, and removes all memory allocations in this formatting path.
