P3391R0 constexpr std::format (Barry Revzin)

[tahonermann]

SG16 reviewed P3391R1 during its 2025-03-26 meeting. The following poll was taken:

• Poll 2: Forward P3391R1 to LEWG.
  • Attendees: 8

    SF	F	N	A	SA
    5	3	0	0	0

  • Strong consensus.

SG16 did not identify any concerns that warrant further follow up. I am therefore removing the SG16 label.
