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: Make build independent of extmod directory. mpy-cross doesn't depend on any code in the extmod directory so completely exclude it from the build (extmod may still be scanned for qstrs but that is controlled by py/py.mk). This speeds up the build a little, and improves abstraction of this component. Also, make -I$(BUILD) take precedence over -I$(TOP) in case there are stray files in the root directory that would be picked up.

mpy-cross: Fix compiler detection for including windows/fmode.c fmode.c should only be included for builds targetting 'pure' windows, i.e. msvc or mingw builds but not when using msys or cygwin's gcc (see #2298). Just checking if the OS is windows and UNAME doesn't have msys stil leaves the gate open for builds with cygwin's gcc since UNAME there is e.g. CYGWIN_NT-6.1-WOW. Fix this by checking for 'mingw' explicitly in the compiler version; both gcc and clang have the -dumpmachine flag so the check should be ok for all platforms.

# Add fmode when compiling with mingw gcc
COMPILER_TARGET := $(shell $(CC) -dumpmachine)

all: Update Makefiles and others to build with new ports/ dir layout. Also renames "stmhal" to "stm32" in documentation and everywhere else.

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().
