Pull request description:
_TLDR:
Currently, `listdescriptors [private=true]` will fail for a non-watch-only wallet if any descriptor has a missing private key(e.g `tr()`, `multi()`, etc.). This PR changes that while making sure `listdescriptors [private=true]` still fails if there no private keys. Closes #32078_
In non-watch-only wallets, it's possible to import descriptors as long as at least one private key is included. It's important that users can still view these descriptors when they need to create a backup—even if some private keys are missing ([#32078 (comment)](https://github.com/bitcoin/bitcoin/issues/32078#issuecomment-2781428475)). This change makes it possible to do so.
This change also helps prevent `listdescriptors true` from failing completely, because one descriptor is missing some private keys.
### Notes
- The new behaviour is applied to all descriptors including miniscript descriptors
- `listdescriptors true` still fails for watch-only wallets to preserve existing behaviour https://github.com/bitcoin/bitcoin/pull/24361#discussion_r920801352
- Wallet migration logic previously used `Descriptor::ToPrivateString()` to determine which descriptor was watchonly. This means that modifying the `ToPrivateString()` behaviour caused descriptors that were previously recognized as "watchonly" to be "non-watchonly". **In order to keep the scope of this PR limited to the RPC behaviour, this PR uses a different method to determine `watchonly` descriptors for the purpose of wallet migration.** A follow-up PR can be opened to update migration logic to exclude descriptors with some private keys from the `watchonly` migration wallet.
### Relevant PRs
https://github.com/bitcoin/bitcoin/pull/24361https://github.com/bitcoin/bitcoin/pull/32186
### Testing
Functional tests were added to test the new behaviour
EDIT
**`listdescriptors [private=true]` will still fail when there are no private keys because non-watchonly wallets must have private keys and calling `listdescriptors [private=true]` for watchonly wallet returns an error**

28a4fcb03c test: check listdescriptors do not return a mix of hardened derivation marker (pythcoiner)
975783cb79 descriptor: account for all StringType in MiniscriptDescriptor::ToStringHelper() (pythcoiner)
Pull request description:
In `MiniscriptDescriptor::ToStringHelper()` only the `StringType::Private` variant of the `type` argument was handled. This PR implements serializing w/ all variants of `StringType` & add a functional test for the descriptor triggering the related issue.
Closes#31694: previously when calling `listdescriptors` RPC on a wallet containing a taproot descriptor w/ a (miniscript) taptree, origins of internal key & taptree were serialized w/ differents hardened derivation markers:
- origin of the internal key were serialized w/ `StringType::Normalized` type (using `h` as marker)
- origins of taptree keys were serialized w/ `StringType::Private` type (using `'` as marker)
Note: Origins in segwit (`wsh()`) miniscript descriptors were also serialized w/ `StringType::Private` type (`'` marker) and are now serialized w/ `StringType::Normalized` type (`h` marker).

Descriptor wallets are already created by default since v23.0, but
since the recent legacy wallet removal this parameter *must* be True
(see commit 9f04e02ffa), i.e. still
passing it wouldn't contain any information for test readers
anymore. So simply drop them in the functional tests in order to
reduce code bloat.

sed -i 's/, descriptors=True//g' $(git ls-files -- 'test/functional' ':(exclude)test/functional/wallet_backwards_compatibility.py')

-END VERIFY SCRIPT-
Removes all legacy wallet specific functional tests.
Also removes the --descriptor and --legacy-wallet options as these are
no longer necessary with the legacy wallet removed.
In the functional tests there are lots of cases where we assert != which
this new util will replace, we also are adding the imports and the new assertion
Require that sqlite is available in order to compile the wallet. Removes
instances of USE_SQLITE since it is no longer possible to not have
sqlite available.
The NO_SQLITE option is dropped from depends.

fe49f06c0e doc: clarify PR 26076 release note (Sjors Provoost)
bd13dc2f46 Switch hardened derivation marker to h in descriptors (Sjors Provoost)
Pull request description:
This makes it easier to handle descriptor strings manually, especially when importing from another Bitcoin Core wallet.
For example the `importdescriptors` RPC call is easiest to use `h` as the marker: `'["desc": ".../0h/..."]'`, avoiding the need for escape characters. With this change `listdescriptors` will use `h`, so you can copy-paste the result, without having to add escape characters or switch `'` to 'h' manually.
Both markers can still be parsed.
The `hdkeypath` field in `getaddressinfo` is also impacted by this change, except for legacy wallets. The latter is to prevent accidentally breaking ancient software that uses our legacy wallet.
See discussion in #15740

This makes it easier to handle descriptor strings manually. E.g. an RPC call that takes an array of descriptors can now use '["desc": ".../0h/..."]'.
Both markers can still be parsed. The default for new descriptors is changed to h. In normalized form h is also used. For private keys the chosen marker is preserved in a round trip.
The hdkeypath field in getaddressinfo is also impacted by this change.
b082f28101 rpc, wallet: use the same `next_index` in listdescriptors and importdescriptors (w0xlt)
Pull request description:
Currently `listdescriptors` RPC uses `next` key to represent `WalletDescriptor::next_index` while `importdescriptors` uses `next_index`. This creates two different descriptor formats.
This PR changes `listdescriptors` to use the same key as `importdescriptors`.

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.
bb822a7af8 wallet, rpc: add listdescriptors private option (S3RK)
Pull request description:
Rationale: make it possible to backup your wallet with `listdescriptors` command
* The default behaviour is still to show public version
* For private version only the root xprv is returned
Example use-case:
```
> bitcoin-cli -regtest -named createwallet wallet_name=old descriptors=true
> bitcoin-cli -regtest -rpcwallet=old listdescriptors true | jq '.descriptors' > descriptors.txt
> bitcoin-cli -regtest -named createwallet wallet_name=new descriptors=true blank=true
> bitcoin-cli -regtest -rpcwallet=new importdescriptors "$(cat descriptors.txt)"
```
In case of watch-only wallet without private keys there will be following output:
```
error code: -4
error message:
Can't get descriptor string.
