Subject: Refactor: Split up CWallet and LegacyScriptPubKeyMan and classes

This moves CWallet members and methods dealing with keys to a new
LegacyScriptPubKeyMan class, and updates calling code to reference the new
class instead of CWallet.

Most of the changes are simple text replacements and variable substitutions
easily verified with:

    git log -p -n1 -U0 --word-diff-regex=.

The only nontrivial chunk of code added is the new LegacyScriptPubKeyMan class
declaration, but this code isn't new and is just selectively copied and moved
from the previous CWallet class declaration. This can be verified with:

    git log -p -n1 --color-moved=dimmed_zebra src/wallet/scriptpubkeyman.h src/wallet/wallet.h

or

    git diff HEAD~1:src/wallet/wallet.h HEAD:src/wallet/scriptpubkeyman.h

This commit does not change behavior.
