Use better types for time.get_clock_info

[sobolevn]

Demo:

>>> import time
>>> time.get_clock_info('time')
namespace(implementation='clock_gettime(CLOCK_REALTIME)', monotonic=False, adjustable=True, resolution=1.0000000000000002e-06)

>>> time.get_clock_info('other')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: unknown clock

CPython tests also call this with "thread_time". Looking at the C source code, that's the only missing name.

Looks like it is also missing from the tests in some places 🤔
I will investigate! Thank you!
