This patch addresses several issues related to the additional specializations for enable_nonlocking_formatter_optimization fomr P3235R3 proposal: * LWG4399 [1]: Apply remove_cvref_t to tuple and pair elements when checking if the direct printing optimization is enabled. * LWG4398 [2]: Disable the direct printing optimization for the standard library container adaptors: queue, priority_queue, and stack. * LWG4400 [3]: Enable the direct printing optimization only for durations that use standard arithmetic types. Conditionally enable it for hh_mm_ss and time_points based on their underlying Duration template argument.
