Given code like the following
```
class Foo:
@process_cached
def bar(self):
pass
```
In Python 3.8 referencing `bar` would not call its `__get__` method.
```
x = Foo().bar
```
However in Python 3.11, making the same call would call the `__get__`
method, permanently replacing the underlying `process_cached` object
with the partial function that references it.
This meant that code to clear the cache would work in Python 3.8 but
would break in 3.11
```
Foo().bar.cache.clear() # Works in 3.8 but not in 3.11
```
In 3.11 this results in the following error:
```
E AttributeError: 'functools.partial' object has no attribute 'cache'
```
To make this compatible in both version, we just add the cache as an
accessible attribute on the partial we generate for our wrapped
function.
The sample function used to automatically convert sets to sequences but that is no longer supported starting in 3.11 so we have to do it manually. Reference: https://docs.python.org/3/library/random.html#random.sample
In Python 3.11 CSV files are allowed to have null characters so the test data is no longer a valid. We update it to not have a valid unicode character to still test this code path correctly. I'm not concerned about the fact that the files with null will get past this test beacause there are other checks on the content of the file that catch if it doesn't have enough or the right fields so this should be a safe change to make to the tests. Relevant Change in Python: python/cpython#71767
The way the patch decorator was being used is not supported in python 3.11. Use the patch decorator to auto generate the correct mock and make the test a bit more readabale. The new change is both 3.8 and 3.11 compatible.
The Hashable object was moved in python 3.3 and support for the old location is dropped in python 3.10 the new location is available in python 3.8 so we can just update this and it should work with both python 3.8 and 3.11 https://docs.python.org/3.8/library/collections.html
This function was removed by python 3.11 so update to the alternate call that is the current recommended replacement. https://docs.python.org/3.11/library/inspect.html#inspect.getfullargspec

Multiple edx-platform Python tests fail when running on 3.11 Update those tests so that they will work correctly when we start testing on 3.11.
This PR does not introduce 3.11 testing because there are other costs and complexities to doing that so it is just making modifications to the tests so that they will be compatible with both versions of the code.
The goal is to land this ahead of the other parts of #34374 so that we can reduce the size of the breaking change PR.
