[issue47005] Improve performance of bytes_repeat

New submission from Pieter Eendebak : The bytearray_repeat and bytearray_irepeat are inefficient for small arrays and a high number of repeats. This can be improved by using the same approach is in the corresponding bytes_repeat method. Microbenchmark: python -m pyperf timeit "b=byte
