Merge #16240: JSONRPCRequest-aware RPCHelpMan
b6fb617aaaad5f9cdd7f2ad2825b253ca792055d rpc: switch to using RPCHelpMan.Check() (Karl-Johan Alm)

0ab8ba1ac65b70f044a5e323b13d098cef33695a rpc: fix RPC help requirements for getblocktemplate (Karl-Johan Alm)
Pull request description:
Every single RPC call has a helper-section at the start, which throws a help string if the user asks for help or if the user provided too few/many arguments.
```C++
const RPCHelpMan help{...};
if (request.fHelp || !help.IsValidNumArgs(request.params.size())) {
throw std::runtime_error(help.ToString());
}
```
or (older version)
```C++
if (request.fHelp || request.params.size() < min || request.params.size() > max)
throw std::runtime_error(
RPCHelpMan{...}.ToString()
);
```
It seems like an obvious improvement, and less copy-pasting, to make `RPCHelpMan` aware of `JSONRPCRequest`, and to let it handle the checks instead. Both of the above become
```C++
RPCHelpMan{...}.Check(request);
```
which means we save roughly 3 lines per RPC command, and the `RPCHelpMan` instance is never referenced afterwards, so the approach is a tiny fraction cleaner.
This is a complete update, sans a few special case locations that had special rules. 623 lines turn into 284 (which includes the addition to `RPCHelpMan`).
