javascript: Add new port targeting JavaScript via Emscripten. In this port JavaScript is the underlying "machine" and MicroPython is transmuted into JavaScript by Emscripten. MicroPython can then run under Node.js or in the browser.

extmod/extmod.mk: Separate out extmod file list from py.mk to extmod.mk. This separates extmod source files from `py.mk`. Previously, `py.mk` assumed that every consumer of the py/ directory also wanted to include extmod/. However, this is not the case. For example, building mpy-cross uses py/ but doesn't need extmod/. This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and explicitly includes `extmod.mk` in ports that use it. Signed-off-by: David Lechner <david@pybricks.com>

javascript: Rework Makefile and GC so it works with latest Emscripten. The GC now works correctly using asyncify and the functions emscripten_scan_stack() and emscripten_scan_registers(). Stack/call depth is monitored via the use of the pystack option. Fixes issue #6738. Signed-off-by: Damien George <damien@micropython.org>

webassembly/Makefile: Change compiler optimisation from O3 to Os. Emscripten strongly advises the use of optimisation when compiling with ASYNCIFY enabled. Testing the difference betwen O3 and Os for various configurations gives: flags firmware.wasm micropython.js perf -O3 -s ASYNCIFY 1342003 212845 0 (baseline) -O3 -s ASYNCIFY -s WASM=0 - 7064750 -30% -O3 367131 196569 +140% -O3 -s WASM=0 - 2818260 +30% -Os -s ASYNCIFY 1135450 213064 +40% -Os -s ASYNCIFY -s WASM=0 - 6239768 -30% -Os 295028 196569 +180% -Os -s WASM=0 - 2271358 +30% The first row is prior to this commit. The second and third columns show firmware size (add them to get the total size). The fourth column shows the approximate change in performance compared to the baseline. The performance was measured using run-perfbench.py and the error was large, up to 20%, although general trends in the change in performance could still be seen. In summary, using using Os instead of O3 makes it a little bit faster in all cases, and smaller output (wasm/js) in all cases. Signed-off-by: Damien George <damien@micropython.org>

shared/readline: Use MP_REGISTER_ROOT_POINTER(). This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root pointer array used by shared/readline.c and removes the registration from all mpconfigport.h files. This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option since not all ports used the same sized array. Signed-off-by: David Lechner <david@pybricks.com>
