Add interfaces::ExternalSigner to let signer objects be passed between
processes and signer code to run in the original process, without
multiple processes linking and running signer code.

Big picture overview in [this gist](https://gist.github.com/Sjors/29d06728c685e6182828c1ce9b74483d).
This PR adds GUI support for external signers, based on the since merged bitcoin/bitcoin#16546 (RPC).
The UX isn't amazing - especially the blocking calls - but it works.
First we adds a GUI setting for the signer script (e.g. path to HWI):

Then we add an external signer checkbox to the wallet creation dialog:

It's checked by default if HWI detects a device. It also grabs the name. It then creates a fresh wallet and imports the keys.
You can verify an address on the device (blocking...):

Sending, including coin selection, Just Works(tm) as long the device is present.
~External signer support is enabled by default when the GUI is configured and Boost::Process is present.~
External signer support remains disabled by default, see https://github.com/bitcoin/bitcoin/pull/21935.

QProgressDialog estimates the time the operation will take (based on
time for steps), and only shows itself if that estimate is beyond
minimumDuration. The default minimumDuration value is 4 seconds, and it
could make users think that the GUI is frozen.
Add WalletClient interface so node interface is cleaner and don't need
wallet-specific methods.
The new NodeContext::wallet_client pointer will also be needed to eliminate
global wallet variables like ::vpwallets, because createWallet(), loadWallet(),
getWallets(), etc methods called by the GUI need a way to get a reference to
the list of open wallets if it is no longer a global variable.
Also tweaks splash screen registration for load wallet events to be delayed
until after wallet client is created.

Pull request description:
This PR is a [followup](https://github.com/bitcoin/bitcoin/issues/16218#issuecomment-625919724) of #16224, and it adds `bilingual_str` type argument support to the `AbortNode()` functions.

Common errors and warnings should be translated when displayed in the
GUI, but not translated when displayed elsewhere. The wallet method
CreateWalletFromFile does not know its caller, so this commit changes it
to return a bilingual_str to the caller.
96cb597325f64cadb3cf43e2cdb3d7c1e2e49891 gui: Avoid redundant tx status updates (Russell Yanofsky)
Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
In `TransactionTablePriv::index`, avoid calling `interfaces::Wallet::tryGetTxStatus` if the status is up to date as of the most recent `NotifyBlockTip` notification. Store height from the most recent notification in a new `ClientModel::cachedNumBlocks` variable in order to check this.
This avoids floods of IPC traffic from `tryGetTxStatus` with #10102 when there are a lot of transactions. It might also make the GUI a little more efficient even when there is no IPC.

UI improvements:
- update remaining GUI wallet labels and tooltips from passwords to passphrases
- improve grammar of labels in askpassphrase dialog and WalletController::closeWallet
