fix: AttackDist, unguardable projectiles, netplay lifebars; refactoring

[potsmugen]

Fix:

• AttackDist now overwrites Hitdef guard.dist as in Mugen, instead of being a separate variable
• AssertSpecial "unguardable" now also affects projectiles
• Fixed typo that made lifebars disappear during netplay
• Fixes AttackDist and HitDef guard.dist interaction #2358
• Fixes Unguardable SCTRL doesn't work for projectiles #2367
• Fixes Lifebars not visible in Network Mode - Nightly Build (February 2025 and later) #2374

Refactor:

• Adjusted ModifyProjectile to only parse the parameters once per projectile loop, which is generally safer
• Removed explod friction Mugen version limits, since it's an Ikemen parameter
• A few more HitDef values now use the "ierrset" approach instead of being set in the bytecode. This is more consistent and safer in the long run
• Flipped Y and Z attack distance parameters for consistency. First parameter is top and second is bottom
• Simplified Z space player push code. The previous "tie breaker" code replaces the main code and is used all the time
• Renamed debug modes to be closer to the documentation ("display" instead of "draw")
