mpy-cross: Add new component, a cross compiler for MicroPython bytecode. This component allows to generate .mpy files (pre compiled bytecode) which can be executed within any MicroPython runtime/VM.

mpy-cross: Use binary file translation mode for creating mpy files on windows This is a fix for https://github.com/micropython/micropython/issues/2209: by default a file created using open() uses text translation mode so writing \n to it will result in the file having \r\n. This is obviously problematic for binary .mpy files, so provide functions for setting the open mode and use binary mode in mpy-cross' main().

mpy-cross: Fix mingw and msys2 compilation When compiling with msys2's gcc there's no need to apply the binary fmode so adjust the Makefile to reflect that. When compiling with mingw we need to include malloc.h since there is no alloca.h, and the 64bit detection in mpconfigport.h needs some adjustment.
