[ledger][testing] Add Ledger instance provider.
Adds a binary that returns Ledger instances.
Will be used for tests that are built outside of peridot because those
don't have access to the necessary ledger::internal API.
TEST=None.

+# Ledger Test Instance Provider
+
+This is a package containing a `ledger_test_instance_provider_bin` binary whose
+purpose is to return a single Ledger instance backed by memfs.
+
+It exists to allow tests built outside of peridot to get access to a Ledger
+instance, a task otherwise impossible because the required API
+(LedgerRepository) is not available outside of peridot.
