py: Expand type equality flags to 3 separate ones, fix bool/namedtuple.

Both bool and namedtuple will check against other types for equality; int,
float and complex for bool, and tuple for namedtuple.  So to make them work
after the recent commit 3aab54bf43 they would
need MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST set.  But that makes all bool and
namedtuple equality checks less efficient because mp_obj_equal_not_equal()
could no longer short-cut x==x, and would need to try __ne__.  To improve
this, this commit splits the MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST flags into 3
separate flags to give types more fine-grained control over how their
equality behaves.  These new flags are then used to fix bool and namedtuple
equality.

Fixes issue #5615 and #5620.
