py/scope: Shrink scope_t struct by 1 machine word.
On 32-bit archs this makes the scope_t struct 48 bytes in size, which fits
in 3 GC blocks (previously it used 4 GC blocks). This will lead to some
savings when compiling scripts because there are usually quite a few scopes,
one for each function and class.
Note that qstrs will fit in 16 bits, this assumption is made in a few other
places.
