This is to fix an outstanding TODO. The test cases is using a range as
this will exist in all builds, but `mp_obj_get_int` is used in many
different parts of code where an overflow is more likely to occur.

Long long big integer support now raises an exception on overflow rather
than returning an undefined result.
Also adds an error when shifting by a negative value.
The new arithmetic checks are added in the misc.h header.

These will run on all ports which support them, but importantly
they'll also run on ports that don't support arbitrary precision
but do support 64-bit long ints.
Includes some test workarounds to account for things which will overflow
once "long long" big integers overflow (added in follow-up commit):
- uctypes_array_load_store test was failing already, now won't parse.
- all the ffi_int tests contain 64-bit unsigned values, that won't parse
as long long.
