7392b8b084be14b75536887b7ff216152d0a3307 miner: clamp options instead of asserting (Pieter Wuille)
Pull request description:
The `BlockAssembler::ClampOptions` function currently doesn't actually clamp most of the provided settings, but asserts that some are in range. This made sense while it was a purely internal interface.
However, with the mining IPC interface exposed in #30510, these options are now externally accessible, and it is not entirely intuitive how to set them. In particular, calling `Mining::createNewBlock` with a default-constructed `BlockCreateOptions` will right now instantly crash the bitcoin node.
This isn't a security issue, as the IPC interface is considered trusted, but it is highly unexpected I think, and rather unergonomical to have the node crash while developing against the interface.
An alternative would be exposing a way for the interface to return a failure, but I think in this case, just correcting to reasonable values is acceptable.

Code review ACK 7392b8b084be14b75536887b7ff216152d0a3307. I think ideally this would throw an exception and return a clear error to the caller, or maybe log as stickies suggested, but clamping is much better than crashing.
