gh-119396: Optimize PyUnicode_FromFormat() UTF-8 decoder (#119398)
Add unicode_decode_utf8_writer() to write directly characters into a
_PyUnicodeWriter writer: avoid the creation of a temporary string.
Optimize PyUnicode_FromFormat() by using the new
unicode_decode_utf8_writer().
Rename unicode_fromformat_write_cstr() to
unicode_fromformat_write_utf8().
Microbenchmark on the code:
return PyUnicode_FromFormat(
"%s %s %s %s %s.",
"format", "multiple", "utf8", "short", "strings");
Result: 620 ns +- 8 ns -> 382 ns +- 2 ns: 1.62x faster.
