ledger-tool: Consolidate ledger-tool specific directories (#32851)

When ledger-tool runs, it may create secondary directories for things
like accounts, accounts-index, etc as not to potentially interfere with
solana-validator's directories. These would show as multiple directories
with ".ledger-tool" appended to the typical directory name.

To more clearly group these items, make the default directories for
snapshots, accounts and accounts-index all within a common "ledger-tool"
directory.
