This commit adds the bytes methods to bytearray, matching CPython. The existing implementations of these methods for str/bytes are reused for bytearray with minor updates to match CPython return types. For details on the CPython behaviour see https://docs.python.org/3/library/stdtypes.html#bytes-and-bytearray-operations The work to merge locals tables for str/bytes/bytearray/array was done by @jimmo. Because of this merging of locals the change in code size for this commit is mostly negative: bare-arm: +0 +0.000% minimal x86: +29 +0.018% unix x64: -792 -0.128% standard[incl -448(data)] unix nanbox: -436 -0.078% nanbox[incl -448(data)] stm32: -40 -0.010% PYBV10 cc3200: -32 -0.017% esp8266: -28 -0.004% GENERIC esp32: -72 -0.005% GENERIC[incl -200(data)] mimxrt: -40 -0.011% TEENSY40 renesas-ra: -40 -0.006% RA6M2_EK nrf: -16 -0.009% pca10040 rp2: -64 -0.013% PICO samd: +148 +0.105% ADAFRUIT_ITSYBITSY_M4_EXPRESS
