Merge bitcoin/bitcoin#22183: Remove `gArgs` from `wallet.h` and `wallet.cpp`

c3c213215b25f3e6f36d46b1d49dfcc3040cee1c Use `context.args` in `src/wallet/load.cpp`. (Kiminuo)
25de4e77feddf9b2f4d134bab5faa26c3e5a764d Use `context.args` in `CWallet::Create` instead of `gArgs`. (Kiminuo)
aa5e7c9471c50771bc77b0ec4e0e0929e4a32eae Fix typo in bitcoin-cli.cpp (Kiminuo)

Pull request description:

  The PR attempts to move us an inch towards the [goal](https://github.com/bitcoin/bitcoin/pull/21244#discussion_r615307465) by using `WalletContext` in `wallet.{h|cpp}` code instead of relying on the global state (i.e. `gArgs`).

  Edit: The PR builds on #19101.
