Issue #25349: Optimize bytes % int

Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X.
_PyBytesWriter is now used to format directly the integer into the writer
buffer, instead of using a temporary bytes object.

Formatting is between 30% and 50% faster on a microbenchmark.
