Mark de Wever 59e66c515a [libc++][format] Switches to Unicode 15.1. (#86543)
In addition to changes in the tables the extended grapheme clustering
algorithm has been overhauled. Before I considered a separate state
machine to implement the rules. With the new rule GB9c this became more
attractive and the design has changed.

This change initially had quite an impact on the performance. By making
the state machine persistent the performance was improved greatly. Note
it is still slower than before due to the larger Unicode tables.
