9. test: Test SIGTERM handling during waitforblockheight call

   Currently when CTRL-C is pressed and there is an active `waitforblockheight`,
   or `waitforblock`, or `waitfornewblock` RPC call, or a mining interface
   `waitTipChanged` IPC call with a long timeout, the node will not shut down
   right away, and will wait for the timeout to be reached before exiting.
   
   This behavior is not ideal and only happens when the node is stopped with
   CTRL-C or SIGTERM. When the node is stopped with `bitcoin-cli stop`, the wait
   calls are interrupted and the node does shut down right away.
   
   The next commit improves node behavior. This commit just adds test coverage to
   simplify the next commit and clarify the change in behavior there.

10. init: Signal m_tip_block_cv on Ctrl-C

    Signal m_tip_block_cv when Ctrl-C is pressed or SIGTERM is received, the same
    way it is currently signalled when the `stop` RPC is called. This lets RPC
    calls like `waitforblockheight` and IPC calls like `waitTipChanged` be
    interrupted, instead of waiting for their original timeouts and delaying
    shutdown.
    
    Historical notes:
    
    - The behavior where `stop` RPC signals `m_tip_block_cv`, but CTRL-C does not,
      has been around since the condition variable was introduced in #30409
      (7eccdaf16081d6f624c4dc21df75b0474e049d2b).
    - The signaling was later moved without changing behavior in #30967
      (5ca28ef28bcca1775ff49921fc2528d9439b71ab). This commit moves it again to
      the Interrupt() function, which is probably the place it should have been
      added initially, so it works for Ctrl-C shutdowns as well as `stop`
      shutdowns.
    - A Qt shutdown bug calling wait methods was fixed previously in #18452
      (da73f1513a637a9f347b64de66564d6cdb2541f8), and this change updates that
      fix to avoid the hang happening again in Qt.
