John Freeman 91e9658217 Fix the package recipe for consumers of libxrpl (#4631)
- "Rename" the type `LedgerInfo` to `LedgerHeader` (but leave an alias
  for `LedgerInfo` to not yet disturb existing uses). Put it in its own
  public header, named after itself, so that it is more easily found.
- Move the type `Fees` and NFT serialization functions into public
  (installed) headers.
- Compile the XRPL and gRPC protocol buffers directly into `libxrpl` and
  install their headers. Fix the Conan recipe to correctly export these
  types.

Addresses change (2) in
https://github.com/XRPLF/XRPL-Standards/discussions/121.

For context: This work supports Clio's dependence on libxrpl. Clio is
just an example consumer. These changes should benefit all current and
future consumers.
