Improves code for remote materials (#87870)

## About The Pull Request
- Moves remote materials attack chain to item interaction level. Another
step in moving away from `attackby()`
- Fixes #40070. Though the timer subsystem maybe affected by FPS, round
start trigger is always done after everything is set up which is now
used by remote materials

## Changelog
🆑
fix: silo connection on some machines won't time out when changing FPS
settings
code: improved attack chain code for silo connection
