Add support for Saffell's Frame "max block mods apply to max resist"

[Blitz54]

Description of the problem being solved:

Saffel's Frame disables the ability to block, and makes any modifiers to max block instead apply to max resistances. I believe this functions as it should, but please let me know if I there's a better way to do it.

Steps taken to verify a working solution:

• Equipping the shield disables block, and prevents any + max block mods from items like The Anvil from applying to max block.
• +5 max block Anvil applies +5 to all resists, including chaos.
• A modified -5 to max block Anvil lowers max res of all resists by 5.
• Melding of the Flesh isn't in PoE2, but regardless we don't need to add the max block calculation there as it affects all resistances equally.

Issue

Modifiers do not show up in the breakdown for Max Res. Not sure how to get them to show up. Would be nice to see, but not necessarily needed.
Also had to hardcode the 75 base max block chance. Probably no issue, but it would be nice to grab it from CalcSetup, not sure how or if it's even worth it though.
