Merge bitcoin/bitcoin#31603: descriptor: check whitespace in keys within fragments

Browse Source 
21e9d39a37 docs: add release notes for 31603 (brunoerg)
a8b548d75d test: `getdescriptorinfo`/`importdescriptors` with whitespace in pubkeys (brunoerg)
c7afca3d62 test: descriptor: check whitespace into keys (brunoerg)
cb722a3cea descriptor: check whitespace in ParsePubkeyInner (brunoerg)
50856695ef test: fix descriptors in `ismine_tests` (brunoerg)

Pull request description:

  Currently, we successfully parse descriptors which contains spaces in the beginning or end of the public/private key within a fragment (e.g. `pk( KEY)`, `pk(KEY )` or `pk( KEY )`). I have noticed that one of the reasons is that the `DecodeBase58` function simply ignore these whitespaces.

  This PR changes the `ParsePubkeyInner ` to reject pubkeys that contain a whitespace at the beginning and/or at the end. We will only check the whitespace in some RPCs (e.g. `importdescriptors`), but an already imported descriptor won't be affected by this check, especially because we store descriptors from `ToString`.

  For context: https://github.com/brunoerg/bitcoinfuzz/issues/72
