Pull request description:

  Closes #11348

  Adds a `-walletdir` parameter which specifies a directory to use for wallets, allowing them to be stored separately from the 'main' data directory. Creates a new `wallets/` directory in datadir if this is the first time running, and defaults to using it if it exists.

  Includes tests and release notes. Things which might need to be considered more:
  - there is no 'lock' on the wallets directory, which might be needed?
  - because this uses a new wallets/ directory by default, downgrading to an earlier version won't see the wallets in that directory (not a big deal though, users can just copy them up to the main dir)
  - jnewbery suggested putting each wallet in its own directory, which is a good idea, but out of scope for this PR IMO. EDIT: this is being done in https://github.com/bitcoin/bitcoin/pull/11687
  - doc/files.md needs updating (will do soon)

  I also considered including  a cleanup by removing caching of data directory paths and instead just initialise them once on startup (c.f. #3073), but decided it wasn't super relevant here will just complicate review.

Custom wallet directories
---------------------
The ability to specify a directory other than the default data directory in which to store
wallets has been added. An existing directory can be specified using the `-walletdir=<dir>`
argument. Wallets loaded via `-wallet` arguments must be in this wallet directory. Care should be taken
when choosing a wallet directory location, as if it becomes unavailable during operation,
funds may be lost.
Default wallet directory change
--------------------------
On new installations (if the data directory doesn't exist), wallets will now be stored in a
new `wallets/` subdirectory inside the data directory. If this `wallets/` subdirectory
doesn't exist (i.e. on existing nodes), the current datadir root is used instead, as it was.
Low-level RPC changes
----------------------
- The deprecated RPC `getinfo` was removed. It is recommended that the more specific RPCs are used:
