[issue46140] Some API methods could take const Py_buffer* instead of Py_buffer *

[David Hewitt]

New submission from David Hewitt <david at hewitt.tech>:

The limited api methods `PyBuffer_GetPointer`, `PyBuffer_FromContiguous`, `PyBuffer_ToContiguous` and `PyMemoryView_FromBuffer` take buffer arguments as `Py_buffer *`.

They do not mutate the buffer info, so could simply take `const Py_buffer *`.

There is already precedent to take `const Py_buffer *` argument in `PyBuffer_IsContiguous`.

I'm going to submit a PR to fix.
