Adding a context parameter ensures that these methods are run in
their own thread and don't block other calls. They were missing
for:
- createNewBlock()
- checkBlock()
The missing parameters were first pointed out by plebhash in
https://github.com/bitcoin/bitcoin/issues/33575#issuecomment-3383290115 and
adding them should prevent possible performance problems and lockups,
especially with #34184 which can make the createNewBlock method block for a
long time before returning. It would be straightforward to make this change in
a backward compatible way
(https://github.com/bitcoin/bitcoin/pull/34184#discussion_r2770232149) but nice
to not need to go through the trouble.
Warning: This is an intermediate, review-only commit. Binaries built from it
should not be distributed or used to connect to other clients or servers. It
makes incompatible changes to the `mining.capnp` schema without updating the
`Init.makeMining` version, causing binaries to advertise support for a schema
they do not actually implement. Mixed versions may therefore exchange garbage
requests/responses instead of producing clear errors. The final commit in this
series bumps the mining interface number to ensure mismatches are detected.

Refactor the mining_create_block_template and mining_wait_next_template
helpers in ipc_util.py to return None if they time out or fail. It makes
the test easier to read and provides a more clear error message in case
of a regression.
There were a few spots that didn't use mining_wait_next_template yet,
which now do.
