  1. Optimize type parameter checks in subtype checking 

    Avoid the use of a nested function, which are a bit slow when compiled
with mypyc. Also avoid a callable value and instead call a function
directly, which allows using faster native calls.

Based on a quick experiment, this speeds up self check by about 3%.

This addresses some of the slowdown introduced in #13303.
