Merge #19969: Send RPC bug fix and touch-ups

Browse source 
f7b331ea85 rpc: add brackets to ConstructTransaction (Sjors Provoost)
d813d26f06 [rpc] send: various touch-ups (Sjors Provoost)
0fc1c685e1 [rpc] send: fix parsing replaceable option (Sjors Provoost)
efc9b85e6f Mark send RPC experimental (Sjors Provoost)

Pull request description:

  Followup based on #16378 nits. It also fixes an argument parsing error (uncaught because the test wasn't sufficiently thorough).

  I marked the RPC as experimental so we can tweak it a bit over the next release cycle.

RPC
---
- A new `send` RPC with similar syntax to `walletcreatefundedpsbt`, including
support for coin selection and a custom fee rate. Using the new `send` method
is encouraged: `sendmany` and `sendtoaddress` may be deprecated in a future release.
support for coin selection and a custom fee rate. The `send` RPC is experimental
and may change in subsequent releases. Using it is encouraged once it's no
longer experimental: `sendmany` and `sendtoaddress` may be deprecated in a future release.
