Fix Stomping Ground and Ferocious Roar not working when using a Talisman

[unrealdreamz]

Summary

Fixes #1676.

Prevents Stomping Ground's support-granted shockwave weapon metadata from making the supported Rampage skill fail its talisman weapon check.

Root Cause

CalcActiveSkill merged weapon requirements from every compatible support into the active skill's weapon check. Stomping Ground is a support gem that grants its own triggered shockwave skill, and its exported weaponTypes metadata belongs to that granted effect. Applying that support metadata to Rampage made Rampage require both a talisman and a two-handed mace, so the skill was disabled as an invalid weapon setup.

Fix

• Keep the active skill's own weapon requirements unchanged.
• Continue respecting support weapon requirements for ordinary supports.
• Do not apply a support gem's weaponTypes as an active-skill requirement when that support gem also grants an active skill.
• Add a regression with Rampage + Stomping Ground on a Changeling Talisman, asserting Rampage remains enabled.

Validation

• git diff --check — passed, CRLF conversion warnings only.
• git diff --cached --check — passed, CRLF conversion warnings only.
• git show --check --stat --oneline HEAD — passed.

I did not run Docker/Busted locally on this machine; the local test path for this repo is container-based and I avoided starting containers or external windows during this contribution pass.

Risk / Rollback

Risk is limited to weapon-type validation for support gems that grant their own active skill. Stomping Ground is currently the only support in the exported support data with both support = true and weaponTypes, so the blast radius is intentionally small. Rollback is the single commit if maintainers prefer a data-side exception instead.

Simplified the fix by removing the weapon type export for support gems
