feat: implement TransactionEventId::event_name and host name resolution

[PhilippGackstatter]

Implements TransactionEventId::event_name and host name resolution.

• Extract not only the event ID but also the event name in build.rs.
• Implements TransactionEventId::event_name to map event ID to name.
• Implements Host::resolve_event for all hosts to improve error messages.

For example, an error in an event handler currently gives:

Error:   × error during processing of event with ID: 11218463077671809423
  ╰─▶ slot ptr 10632 is uninitialized
      ╭─[~/miden-protocol/target/debug/build/miden-protocol-8f28cfe76b3927bf/out/asm/kernels/transaction/lib/account.masm:1634:5]
 1633 │ 
 1634 │     emit.ACCOUNT_STORAGE_BEFORE_GET_MAP_ITEM_EVENT
      ·     ──────────────────────────────────────────────
 1635 │     # => [slot_ptr, KEY]
      ╰────

We now get the same error message, but with:

Error:   × error during processing of event 'miden::protocol::account::storage_before_get_map_item' (ID: 11218463077671809423)

So the event name is contained in the error (though we already knew that from the constant name too).

There may be other benefits of implementing Host::resolve_event but, I'm not sure.

closes #2043
