About whether to add arch attribute in sys.impelemtation

[rruuaanng]

Proposal:

# Add a code block here, if required

Actually, the discussion in the PR failed because no one decided whether to merge it or not (it seems that the only supporter is @zooba).
The newly added arch is used to get the current build architecture in Windows (it comes from python.props). What do you think?

Has this already been discussed elsewhere?
