100% Match / Linked Dolphin SDK

[zcanann]

Process for creating this PR, agent assisted:

• Pulled in about ~10 decomp projects with good SDK progress
• Created python scripts to signature match our incomplete SDK code against games with similar SDKs
• Relentlessly copy the code from similar games until it matched and linked.
• Internet searches were NOT used in this. Only existing decomp projects (TP, TWW, MP4, Pikmin 2, etc)
