Review note: The changes are complete, because self.options.descriptors
is set to None in parse_args (test_framework.py).
A value of None implies -disablewallet, see the previous commit.
So if a call to add_wallet_options is missing, it will lead to a test
failure when the wallet is compiled in.

Pull request description:
A user reported on [stackexchange](https://bitcoin.stackexchange.com/q/115742/48884) that they were unable to sign for a `multi_a` script using a wallet that only had the corresponding keys (i.e. it did not have the `multi_a()` descriptor). This PR fixes this issue.
Additionally, `wallet_taproot.py` is modified to test for this scenario by having another wallet in `do_test_psbt` which contains descriptors that only have the keys involved in the descriptor being tested. `wallet_taproot.py` was also modified to create new wallets for each test case rather than sharing wallets throughout as the sharing could result in the signing wallet having the keys in a different descriptor and accidentally result in failing to detect a test failure.
The changes to the test also revealed a similar issue with `rawtr()` descriptors, which has also been fixed by checking if a descriptor can produce a `SigningProvider` for the Taproot output pubkey.

To avoid a wallet potentially being able to sign a transaction using
keys from descriptors imported in previous tests, make new wallets for
each test case rather than sharing them.
db27ac9354 tests: Ensure sorted/multi_a descriptors always generate different addrs (Andrew Chow)
Pull request description:
Sometimes the multi_a and sortedmulti_a descriptors will produce some of the same addresses in the tests. This causes the wallets to start generating addresses at a different index as they detect that one of the addresses is used. This subsequently causes a test failure.
To avoid this problem, use descriptors that will produce unique addresses by putting one of the multi_a in a different branch.

fa3e0da06b policy: Treat taproot as always active (MarcoFalke)
Pull request description:
Now that taproot is active, it can be treated as if it was always active for policy for the next major release. This simplifies the code and changes two things:
* Importing `tr` descriptors can be done before the chain is fully synced. This is fine, because the wallet will already generate `tr` descriptors by default (regardless of the taproot status) after commit 47fe7445e7.
* Valid taproot spends won't be rejected from the mempool before taproot is active. This is strictly speaking a bugfix after commit 47fe7445e7, since the wallet may generate taproot spends before the chain is fully synced. For example, a slow node or a purposefully offline node. Currently, the wallet needs the mempool to account for change. See https://github.com/bitcoin/bitcoin/issues/11887.
A similar change was done for segwit v0 in https://github.com/bitcoin/bitcoin/pull/13120 .
This effectively reverts commit c5ec0367d7.

This introduces Taproot wallet support. I fixed all the merge conflicts
and ensured that the tests pass, but this is still using the old sighash
(before Russell/Sanket/I redid it) so is not actually production ready.
Will be fixed when we bring Elements #1002 in.
Does the bare minimum to introduce Taproot wallet support with CT; just
adds a CPubKey blinding_pubkey to the taproot destination variant and
updates some visitors.
In future when we define blech32 we will need to make sure we are using
that encoding and using the pubkey.

177c15d2f7 Limit LegacyScriptPubKeyMan address types (Andrew Chow)
Pull request description:
Currently bech32m addresses are classfied as bech32. Because bech32m is incompatible with bech32, we need to define a new `OutputType` for it so that it can be handled correctly. This PR adds `OutputType::BECH32M`, updates all of the relevant `OutputType` classifications, and handle requests for bech32m addresses. There is now a `bech32m` address type string that can be used.
* `tr()` descriptors now report their output type as `OutputType::BECH32M`. `WtinessV1Taproot` and `WitnessUnknown` are also classified as `OutputType::BECH32M`.
* Bech32m addresses are completely disabled for legacy wallets. They cannot be imported (explicitly disallowed in `importaddress` and `importmulti`), will not be created when getting all destinations for a pubkey, and will not be added with `addmultisigaddress`. Additional protections have been added to `LegacyScriptPubKeyMan` to disallow attempting to retrieve bech32m addresses.
* Since Taproot multisigs are not implemented yet, `createmultisig` will also disallow the bech32m address type.
* As Taproot is not yet active, `DescriptorScriptPubKeyMan` cannot and will not create a `tr()` descriptor. Protections have been added to make sure this cannot occur.
* The change address type detection algorithm has been updated to return `bech32m` when there is a segwit v1+ output script and the wallet has a bech32m `ScriptPubKeyMan`, falling back to bech32 if one is not available.
