PR Summary

Added the ability to pass in a list of wedgeproperty dicts, one for each wedge of the pie. Follow on to #2923, would probably address #3134 , inspired by twitter convo

Yes, I know it can be achieved via loop - see the fig comparison test in this PR - but we were already looping over the wedges inside the function to set all the other properties so the major addition is testing if the input is a dict or list of dicts. <- this could possibly be factored into a cbook function, my guess being 'if thing not list wrap in repeat' is not uncommon in the codebase.

Current Iteration

1. Changed this to a hatch kwarg based on the call, added tests + whats new example.
2. cleaned up pct/label loc docs from [ENH]: Ability to Swap autopct and label positions #24789, reordered docs to mostly match signature, and added sentence that wedgeprop takes precedence over other parameter setting (in current implementation, seemed sorting this out was out of scope for this PR)

x = [0.3, 0.3, 0.1]
fig, ax = plt.subplots()
ax.pie(x, hatch=['/', '+', '.'])

which would produce roughly

I'll put in a what's new and example if there's consensus on this going in.
