55ce4b7c - Reapply "[ORC] Simplify WaitingOnGraph::Coalescer::remove." (#183231)

Reapply "[ORC] Simplify WaitingOnGraph::Coalescer::remove." (#183231) This reapplies 85354c6d8bc, which was reverted in d7347c0b81a due to bot failures. In this commit further changes are made to address the bot failure, and general readability. WaitingOnGraph::Coalescer::remove is renamed WaitingOnGraph::Coalescer::erase, since its behavior is now similar to common container erase operations. WaitingOnGraph::Coalescer::clear is provided to enable a fast reset of Coalescer state. SuperNodeBuilder::takeSuperNodes is updated to clear the Coalescer state before returning the SuperNodes, ensuring that future calls to SuperNodeBuilder::add do not trip the assert that caused the builder failures.
