Fix broken mp_stack_check: force mp_stack_ctrl_init() and mp_stack_usage() not to be inlined even with -flto

Switch exception throwing to mp_raise helpers. It saves a little code space each time to share the call.

vm: Support strict stackless mode, with proper exception reporting.
...
I.e. in this mode, C stack will never be used to call a Python function,
but if there's no free heap for a call, it will be reported as
RuntimeError (as expected), not MemoryError.

stackctrl: Encode "recursion depth exceeded" message as qstr.
...
So corresponding exception can be thrown even under tight memory conditions.

py: Put all global state together in state structures.
...
This patch consolidates all global variables in py/ core into one place,
in a global structure. Root pointers are all located together to make
GC tracing easier and more efficient.

py: Add portable framework to query/check C stack usage.
...
Such mechanism is important to get stable Python functioning, because Python
function calling is handled with C stack. The idea is to sprinkle
STACK_CHECK() calls in places where there can be C recursion.
TODO: Add more STACK_CHECK()'s.
