`RpcImportParams` keeps track of the scriptPubKey derivation index to start from for the next call to `importdescripts`/`importmulti`, thus avoiding re-importing into Bitcoin Core.
* Add `RpcSyncParams::page_size` that restricts req/resp array count for various RPC calls. * Add `pagenated_import` function.
Whenever the transport errors with "WouldBlock" we wait a bit and retry the call. Related to bitcoindevkit#650, should at least fix the errors with RPC

Bitcoin Core returns code -4 during scriptPubKey/descriptor import when it is still rescanning the wallet. This PR waits until the rescan completes before continuing sync as if it was a successful import. The caveat of this approach is that a sync cycle may miss out on importing some scriptPubKeys. Also, re-import logic is not ideal as network interruptions or parallel requests will result in strange behavior. TODO: This may not be this best solution.

@afilini do you think this is still worth working on? |

This PR replaces #707 (which attempted to fix #650), but is based on top of work done in #740.
Description
Refer to #707 and #740
I don't think we can ever fix #650 fully, however the work done in this PR seems to reduce the failure rate.
In addition to the work done by @afilini in #707, this PR introduces logic that catches error code -4 during descriptor/scriptPubKey import, and treats it like a successful import (so we continue syncing as usual). The caveat of this is that some sync cycles will miss out on importing some scriptPubKeys/descriptors, but is this better than a complete failure?
