Merge #21575: refactor: Create blockstorage module 
fadcd3f78e doc: Remove irrelevant link to GitHub (MarcoFalke)
fa121b628d blockstorage: [refactor] Use chainman reference where possible (MarcoFalke)
fa0c7d9ad2 move-only: Move *Disk functions to blockstorage (MarcoFalke)
fa91b2b2b3 move-only: Move AbortNode to shutdown (MarcoFalke)
fa413f07a1 move-only: Move ThreadImport to blockstorage (MarcoFalke)
faf843c07f refactor: Move load block thread into ChainstateManager (MarcoFalke)

Pull request description:

  This picks up the closed pull request #21030 and is the first step toward fixing #21220.

  The basic idea is to move all disk access into a separate module with benefits:
  * Breaking down the massive files init.cpp and validation.cpp into logical units
  * Creating a standalone-module to reduce the mental complexity
  * Pave the way to fix validation related circular dependencies
  * Pave the way to mock disk access for testing, especially where it is performance critical (like fuzzing)

ACKs for top commit:
  promag:
    Code review ACK fadcd3f78e, checked (almost) moved only changes. This is a nice tidy up change and doesn't change behavior. Easily reviewed commit by commit.
  jamesob:
    ACK fadcd3f78e ([`jamesob/ackr/21575.1.MarcoFalke.refactor_create_blocksto`](https://github.com/jamesob/bitcoin/tree/ackr/21575.1.MarcoFalke.refactor_create_blocksto))
  ryanofsky:
    Code review ACK fadcd3f78e. New organization makes sense, moves extraneous things outside of validation.cpp. PR is also easy to review with helpfully split up moveonly commits.

README.md

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.
