Merge bitcoin/bitcoin#29612: rpc: Optimize serialization and enhance metadata of dumptxoutset output 
542e13b293 rpc: Enhance metadata of the dumptxoutset output (Fabian Jahr)
4d8e5edbaa assumeutxo: Add documentation on dumptxoutset serialization format (Fabian Jahr)
c14ed7f384 assumeutxo: Add test for changed coin size value (Fabian Jahr)
de95953d87 rpc: Optimize serialization disk space of dumptxoutset (Fabian Jahr)

Pull request description:

  The second attempt at implementing the `dumptxoutset` space optimization as suggested in #25675. Closes #25675.

  This builds on the work done in #26045, addresses open feedback, adds some further improvements (most importantly usage of compact size), documentation, and an additional test.

  The [original snapshot at height 830,000](https://github.com/bitcoin/bitcoin/pull/29551) came in at 10.82 GB. With this change, the same snapshot is 8.94 GB, a reduction of 17.4%.

  This also enhances the metadata of the output file and adds the following data to allow for better error handling and make future upgrades easier:
  - A newly introduced utxo set magic
  - A version number
  - The network magic
  - The block height

src/node/

The src/node/ directory contains code that needs to access node state (state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar classes).

Code in src/node/ is meant to be segregated from code in src/wallet/ and src/qt/, to ensure wallet and GUI code changes don't interfere with node operation, to allow wallet and GUI code to run in separate processes, and to perhaps eventually allow wallet and GUI code to be maintained in separate source repositories.

As a rule of thumb, code in one of the src/node/, src/wallet/, or src/qt/ directories should avoid calling code in the other directories directly, and only invoke it indirectly through the more limited src/interfaces/ classes.

This directory is at the moment sparsely populated. Eventually more substantial files like src/validation.cpp and src/txmempool.cpp might be moved there.
