[issue41262] Convert memoryview to Argument Clinic

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

The proposed PR converts Objects/memoryobject.c to Argument Clinic.

Advantages:

* Highly optimized code is used to parse arguments instead of slow PyArg_ParseTupleAndKeywords().
* All future improvements of argument parsing (better performance or errors handling) will be automatically applied to memoryobject.

Previously Argument Clinic was used for memoryview.hex().
