Optimize keep_top_bit() in heapq module by using _Py_bit_length() #124165
Description
Feature or enhancement
Proposal:
The keep_top_bit() function in the heapq module currently shifts bits manually to determine the top bit. This can be optimized by using the _Py_bit_length() function, which improves efficiency, especially on hardware that supports specific instructions like bsr on x86 architecture.
