524f981bb8 Bugfix: Miner: Don't reuse block_reserved_weight for "block is full enough to give up" weight delta (Luke Dashjr)

Pull request description:

  PR #30356 incorrectly changed a constant of `4000` to `m_options.coinbase_max_additional_weight` in the check for when to give up finding another transaction to fill the block:

  ```diff
               if (nConsecutiveFailed > MAX_CONSECUTIVE_FAILURES && nBlockWeight >
  -                    m_options.nBlockMaxWeight - 4000) {
  +                    m_options.nBlockMaxWeight - m_options.block_reserved_weight) {
                   // Give up if we're close to full and haven't succeeded in a while
                   break;
               }
  ```

  But this constant did not deal with the reserved weight at all. It was in fact simply checking if the block was close to full, and if so, giving up finding another transaction to pad it with after `MAX_CONSECUTIVE_FAILURES` failed attempts.

  It doesn't seem very logical to reuse the reserve weight for this purpose, and it would be overcomplicated to add yet another setting, so this PR changes it to a new constexpr.

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.
