[issue38366] dataclasses: generate the _hash_action table from the if-else tree

[Io Mintz]

New submission from Io Mintz <benjabean1 at gmail.com>:

The dataclasses._hash_action table is currently a bit hard to read. It could be generated once from the if-else tree written in https://bugs.python.org/issue32929#msg312829 instead, which would both be easier to read and easier to maintain, while still maintaining the efficiency of the current dictionary.
