Addresses part of #14674.

This PR makes cudf.pandas aware of the BaseOffset type. Because of the way isinstance() checks work on proxy types*, we will now pass instance checks like:

freq = "D"
assert isinstance(pd.tseries.frequencies.to_offset(freq), pd.tseries.offsets.BaseOffset)

*proxy types appear to be related to each other in the same way as their corresponding slow types. So if A inherits from B, then ProxyA appears to inherit from ProxyB even though they are not actually related by inheritance.
