[issue46055] Speed up binary shifting operators

[Mark Dickinson]

Two separate significant improvements have been pushed: thanks, Xinhang Xu!

The original PR also contained a reworking of the general case for right-shifting a negative integer. The current code (in main) for that case does involve some extra allocations, and it ought to be possible to write something that doesn't need to allocate temporary PyLongs.
