Assuming proper C99 language support, we can select "the int type as big as
a pointer" (most of the time) or "the 64-bit int type" (nanboxing with
REPR_D), and then define everything else automatically.
This simplifies port configuration files. And the types can still be
overridden if needed.

This is a pretty fundamental module, and even minimal ports like unix and
zephyr minimal have it enabled. So, enabled it by default at the lowest
feature level.
Most things in the `sys` module are configurable, and off by default, so it
shouldn't add too much to ports that don't already have it enabled (which
is just the minimal port).
Also note that `sys` is still disabled on the bare-arm port, to keep that
ultra minimal. It means we now have bare-arm without `sys` and the minimal
port with `sys`. That will allow different code size comparisons if/when
new `sys` features are added.

This was copied from minimal/mpconfigport.h, but it doesn't make sense
for general ports.
Add a comment to minimal/mpconfigport.h to explain why it specifically
overrides it.

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.

For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.
This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

Now that there are feature levels, and that this port uses
MICROPY_CONFIG_ROM_LEVEL_MINIMUM, it's easy to see what optional features
can be disabled. And this commit disables them.

Update minimal port to use the new "minimal" rom level config (this is a
no-op change, the binary is the same size and contains the exact same
symbols).

Changes are:
- string0 is no longer built when building for host as the target, because
it'll be provided by the system libc and may in some cases clash with the
system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
from mpconfigport.h to make the configuration a bit more minimal, eg as
a better starting point for new ports.
To enable lazy loading of submodules (among other things), which is very
useful for MicroPython libraries that want to have optional subcomponents.
Disabled explicitly on minimal ports.
Configurable via MICROPY_PY_BUILTINS_STR_COUNT. Default is enabled.
Disabled for bare-arm, minimal, unix-minimal and zephyr ports. Disabling
it saves 408 bytes on x86.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
