calc_scaling operation override

[real-niacat]

allows cards in calc_scaling to provide an override operation (e.g. making all other scaling jokers scale multiplicitively)

sorry for no lsp defs i didnt see anything relating to the arguments of calc_scaling's return values

Additional Info:

• I didn't modify api's or I've made a PR to the wiki repo.
• I didn't modify api's or I've updated lsp definitions.
• I didn't make new lovely files or all new lovely files have appropriate priority.

Is it ok that multiple jokers with that effect would just override each other?

Because of #1014 maybe makes sense to make some kind of util function to apply effect of calc_scaling?

i think its fine if multiple cards override each other like this, idk how you would cleanly implement it w/o having one take priority over another
