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.

Pull request description:

* A refactor to expose ComputeTapleafHash and ComputeTaprootMerkleRoot from script/interpreter
* A tiny change to make `getaddressinfo` report tr() descriptors as solvable (so that inferred descriptors are shown), despite not having signing code for them.
* Logic to infer the script tree back from TaprootSpendData, and then use that to infer descriptors.

We don't want the legacy wallet to ever have bech32m addresses so don't
allow importing them. This includes addmultisigaddress as that is a
legacy wallet only RPC
Additionally, bech32m multisigs are not available yet, so disallow them
in createmultisig.

Pull request description:
This is a subset of #21365, to aide review.
This adds support `tr(KEY)` or `tr(KEY,SCRIPT)` or `tr(KEY,{{S1,{{S2,S3},...}},...})` descriptors, describing Taproot outputs with specified internal key, and optionally any number of scripts, in nested groups of 2 inside `{`/`}` if there are more than one. While it permits importing `tr(KEY)`, anything beyond that is just laying foundations for more features later.
Missing:
* Signing support (see #21365)
* Support for more interesting scripts inside the tree (only `pk(KEY)` is supported for now). In particular, a multisig policy based on the new `OP_CHECKSIGADD` opcode would be very useful.
* Inferring `tr()` descriptors from outputs (given sufficient information).
* `getaddressinfo` support.
* MuSig support. Standardizing that is still an ongoing effort, and is generally kind of useless without corresponding PSBT support.
* Convenient ways of constructing descriptors without spendable internal key (especially ones that arent't trivially recognizable as such).

e6fe1c37d0 rpc: Improve avoidpartialspends and avoid_reuse documentation (Fabian Jahr)
8f073076b1 wallet: Increase OUTPUT_GROUP_MAX_ENTRIES to 100 (Fabian Jahr)
Pull request description:
Follow-up to #17824.
This increases OUTPUT_GROUP_MAX_ENTRIES to 100 which means that OutputGroups will now be up to 100 outputs large, up from previously 10. The main motivation for this change is that during the PR review club on #17824 [several participants signaled](https://bitcoincore.reviews/17824.html#l-339) that 100 might be a better value here.
I think fees should be manageable for users but more importantly, users should know what they can expect when using the wallet with this configuration, so I also tried to clarify the documentation on `-avoidpartialspends` and `avoid_reuse` a bit. If there are other additional ways how or docs where users can be made aware of the potential consequences of using these parameters, please let me know. Another small upside is that [there seem to be a high number of batching transactions with 100 and 200 inputs](https://miro.medium.com/max/3628/1*sZ5eaBSbsJsHx-J9iztq2g.png)([source](https://medium.com/@hasufly/an-analysis-of-batching-in-bitcoin-9bdf81a394e0)) giving these transactions a bit of a larger anonymity set, although that is probably a very weak argument.

Fixes#21299
Rather than 3 different messages that are confusing / leak
implementation details, use a single message, that is similar to other
wallet related messages. i.e:
"Compiled without sqlite support (required for descriptor wallets)".
This commit moves the ExternalSigner class and RPC methods out of the wallet module.
The enumeratesigners RPC can be used without a wallet since #21417.
With additional modifications external signers could be used without a wallet in general, e.g. via signrawtransaction.
The signerdisplayaddress RPC is ranamed to walletdisplayaddress because it requires wallet context.
A future displayaddress RPC call without wallet context could take a descriptor argument.
This commit fixes a rpc_help.py failure when configured with --disable-wallet.

Pull request description:
This change is needed to fix the `rpc_help.py` test failing in #10102: https://cirrus-ci.com/task/5469433013469184?command=ci#L2275
The [`CRPCTable::dumpArgMap`](16b784d953/src/rpc/server.cpp (L492)) method currently works by casting RPC `unique_id` integer field to a function pointer, and then calling it. The `unique_id` field wasn't supposed to be used this way (it's meant to be used to detect RPC aliases) and as a result, this code segfaults in the `rpc_help.py` test in multiprocess PR #10102 because wallet RPC functions aren't directly accessible from the node process.
Fix this by adding a new `GET_ARGS` RPC request mode to retrieve argument information similar to the way the `GET_HELP` mode retrieves help information.

Pull request description:
Adds `parent_desc` field to the `getaddressinfo` RPC to export a public descriptor. Using the given address, `getaddressinfo` will look up which `DescriptorScriptPubKeyMan` can be used to produce that address. It will then return the descriptor for that `DescriptorScriptPubKeyMan` in the `parent_desc` field. The descriptor will be in a normalized form where the xpub at the last hardened step is derived so that the descriptor can be imported to other wallets. Tests are added to check that the correct descriptor is being returned for the wallet's addresses and that these descriptors can be imported and used in other wallets.
As part of this PR, a `ToNormalizedString` function is added to the descriptor classes. This really only has an effect on `BIP32PubkeyProvider`s that have hardened derivation steps. Tests are added to check that normalized descriptors are returned.
