[mypyc] Add isinstance primitives for complex, type, range, slice and memoryview

[rheard]

isinstance(x, complex) wasn't specialized, so every call looked up builtins.complex by name and went through PyObject_IsInstance. Because the tuple fast path from #19949 only applies when every member is a primitive type, isinstance(x, (float, complex)) was worse still: it built a new tuple on every call, and float lost its fast path too. This is an issue I have run into in my personal projects.

This adds isinstance primitives for complex, type, range, slice and memoryview (PyComplex_Check, PyType_Check, etc.), plus direct type object loads for complex, slice and memoryview so things like type(x) is complex don't go through builtins either. Tuples such as (float, complex) and (bytes, bytearray, memoryview) now use the existing chained checks.

Also fixes a typo in the name of the isinstance(obj, int) primitive (builtints.isinstance).
