Also re-`static`'d a method in src/script/standard.cpp which we had made globally
visible for some historical reason, but which I noticed diffing that file against
upstream.
This adds a `TxoutType::WITNESS_V1_TAPROOT` for P2TR outputs, and permits spending
them in standardness rules. No corresponding `CTxDestination` is added for it,
as that isn't needed until we want wallet integration. The taproot validation flags
are also enabled for mempool transactions, and standardness rules are added
(stack item size limit, no annexes).

A templated BaseHash does not allow for automatic conversion, thus
conversions much be explicitly allowed / whitelisted, which will
reduce the risk of unintended conversions.
These types are equivalent, in data etc, so they need only their
data cast across.
Note a function is used rather than a casting
operator as CKeyID is defined at a lower level than script/standard
3351c91ed4 refactor: Make CScriptVisitor stateless (João Barbosa)
Pull request description:
`CScriptVisitor` was added in 1025440184 (#1357) and the visitor return type was never used. Now `CScriptVisitor` is stateless and `CScript` is the return type.

Moves all of the various SigningProviders out of sign.{cpp,h} and
keystore.{cpp,h}. As such, keystore.{cpp,h} is also removed.
Includes and the Makefile are updated to reflect this. Includes were largely
changed using:
git grep -l "keystore.h" | xargs sed -i -e 's;keystore.h;script/signingprovider.h;g'
